"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Introduction: India is a major contributor to both maternal and neonatal death worldwide. Majority of these fatalities can be averted by adequate utilisation of Antenatal Care (ANC) services. Large scale surveys like National Family Health Survey follow hieratical characters in which subjects within the clusters are often correlated. The ordinary logistic model ignores this correlation and provide compromised estimate of effect size of predictors. Multilevel model that incorporates correlation is the appropriate method.

Aim: To demonstrate the adequacy of multilevel logistic model over ordinary logistic model in hieratical data sets with ANC visits >4 and delivery assisted by Skilled Birth Attendant (SBA).

Materials and Methods: This retrospective, cross-sectional study was conducted at the Institute of Medical Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India, from October 2021 to March 2022. The data of 174607 women, who delivered the children within five years, obtained using cluster sampling, from country wide survey during 20th January 2015 to 4th December 2016 (India’s National Family Health Survey-IV) was used. Firstly, the model adequacy of ordinary and multilevel logistic models was evaluated for ANC >4 visits and delivery assisted by SBA, the same data set of fourth round National Family Health Survey by considering the outcomes;. Thereafter, predictors of late or no registration of pregnancy were identified using three level logistic model.

Results: Because of high Variance Partition Coefficients (VPC) at state and district levels, the multilevel model applied on components ANC >4 visits and delivery assisted by SBA suggested better accuracy of the multilevel logistic model (-2Log L=189334 for ANC >4 visits and 141148 for delivery assisted by SBA) than the ordinary logistic model (-2Log L=220268 for ANC >4 visits and 151978 for delivery assisted by SBA). For the late (registration in third trimester of pregnancy) or no registration of pregnancy, each predictor was found significantly associated in which the most important were women’s education, child birth order, caste and wealth quintile.

Conclusion: The present study concluded that multilevel logistic model in clustered design data was useful instead of individual level for more precise estimate of effect size of the predictors.

Maternal and child health remain an intimidating challenge to the healthcare system worldwide. Antenatal Care (ANC) is an opportunity to promote a positive pregnancy experience and improved maternal and child survival (1). India is the key contributors for both maternal and neonatal death globally. More than 100 maternal deaths per lakh live births and over 23.7 neonatal deaths per 1000 live births occur each year (2),(3). Majority of these deaths can be averted by adequate utilisation of ANC services (2),(3). Several studies had reported by analysing clustered data and reported mother’s age at childbirth, parity, unwanted pregnancy, education and exposure to specific health knowledge in explaining the utilisation of ANC services (4),(5),(6),(7),(8). But these studies findings were based on individual level logistic regression model which may be inappropriate for hieratical data structure (9).

Large sample studies usually follow cluster designs which are hieratical in nature i.e., subjects show similarity within the cluster and dissimilarity between the clusters. Clustering effects could be seen at different levels; for example, nation wide sampled mothers showed substantial inter and intrastate disparity in utilisation of ANC services (7). This disparity could be present even at lower levels of clusters too, such as district levels, block levels and so on (10).

The analysis carried at individual level to identify the predictors of an outcome in clustered data fails to take into account the clustering effect and hence, the findings may not be valid which will influence the correct framing of the policy and programmatic agenda; while multilevel modelling is a statistical technique that extends ordinary logistic regression method by incorporating the existence of inherent correlation within the clusters (11). Here, the units at lower level (level-1) are individuals who are nested within units at higher level (districts: level-2) and the districts are again nested within units at the next higher level (states: level-3).The main strength of multilevel modelling is its power and flexibility, and ability to model a wide range of scenarios and situations. As with all modelling, the weaknesses lie in the quality of the available data and problems with setting up models correctly to represent the important underlying relationships (12).

In a study by Yusuf B et al., while comparing the ordinary and multilevel logistic models with hierarchal data on violent behaviour among secondary school students in Ibadan, Nigeria, authors recommended the use of multilevel model approach for valid decision (9). Thus, the past analysis on the National Family Health Survey-IV (NFHS-IV) data set by using ordinary logistic model may not be precise for the estimated effect size of the identified predictors (4),(13). Hence, present study was conducted to demonstrate the adequacy of multilevel logistic model over ordinary logistic model in hieratical datasets with antenatal care (ANC) visits ≥4 and delivery assisted by Skilled Birth Attendant (SBA) as the outcome variables and also to identify the predictors of late or no registration of pregnancy for ANC services using multilevel logistic model.

Material and Methods

This retrospective, cross-sectional study was conducted at the Institute of Medical Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India from October 2021 to March 2022. The survey was approved by the International Institute for Population Sciences (IIPS) Ethical Review Board in India and the institutional review boards of the funding agencies and the technical assistance agencies (14).

Inclusion criteria: The outcome variables such as ANC visits >4 as suggested by World Health Organisation (WHO) and delivery assisted by SBA i.e., Doctor/Nurse/Lady Health Visitor/Auxiliary Nurse Midwife/other health professionals for the comparison of adequacy of ordinary and multilevel logistic regression models considered were included in the study (15),(16).

Exclusion criteria: Data of subjects with the missing information on one or more required variables were excluded from the study.

Sample size: The data of 174607 women given birth within five years from the India’s NFHS-IV (16), following the inclusion and exclusion criteria, were subjected to analysis.

Data Collection

The data set used was obtained from India’s National Family Health Survey (NFHS-IV) conducted in 2015 to 2016, across 640 districts of 29 states including all seven union territories of India. Respondents were selected following a probability-based cluster sampling procedure in which sampling frames were made on the basis of non overlapping units of geography called Primary Sampling Units (PSUs) i.e., by states and urban and rural areas within each state. At the second stage, a fixed proportion of households were selected using systematic sampling within each PSU (14).

The three levels PSU were:

• Level-1: of 174607 individuals
• Level-2: individuals nested within 640 districts
• Level-3: districts nested within 36 states and union territories

Thereafter, predictors of late or no registration of pregnancy were identified (4),(7). The predictors for the models considered with their categories were current age of women (Age groups: 15-19 years, 20-34 years, 35-49 years), women’s education (no education, primary, secondary, higher), child birth order (1st, 2nd, 3rd, 4th, 5th or ≥6), religion (Hindu, Muslim, others), caste {Scheduled Castes (SCs), Scheduled Tribes (STs), Other Backward Caste (OBC), Others}, wealth quintile (poorest, poorer, middle, richer, richest), distance to health facility (no problem, big problem, not a big problem), place of residence (urban, rural) (14). The analysis was carried by using the ordinary logistic regression model that ignore the hieratical nature of data and thereafter by using the three level mixed effects logistic regression model for ANC visits >4 and delivery assisted by SBA to compare the model adequacy (11). For interpretation, odds ratios (ORs) and 95% confidence intervals (CIs) were reported.

Models

I. Verifying Variance Partition Coefficient (VPC): It explains what proportion of total variance is attributable to variation within groups and between groups and by definition, it is the ratio of variance for a level to the total variance. The VPC at state and district levels were obtained by using the following expressions as (17):


Where, σ2s0=Var(s0k); i.e., variance between states, σ2d0 =Var(d0jk); i.e., variance between district within state and (π2/3)Ëœ3.29 refers to the standard logistic distribution, i.e., the assumed level-1 variance component.

II. Ordinary logistic model (18): Let (1-πi) denote the probability of incidence and no incidence of the binary outcome to the ith individual (i=1,2.......,n) for the outcome with vector of predictors X: (X1X2.....Xp) the logit function of the ordinary logistic model is expressed as:

Logit (πi)=β0+β'X

Where, β0 represents the log odds of random effect associated with the individuals when each predictor equals to zero and β' is the transpose of vector of regression coefficient βi associated with the predictor measuring the change in log odds of incidence of the outcome.

III. Multilevel mixed effect model (19): Let πijk and (1-πijk) denote the probability of incidence and no incidence of the binary outcome to the individual of the district in state/union territory. For the outcome with vector of predictors X; the logit function of the multilevel mixed effect logistic model is expressed as:

Logit (πijk)=β0+β'X+(d0jk+s0k)

Where, β0 represents the log odds of random effects associated with the individuals, s0klog odds of random effects associated with state and d0jklog odds of random effects associated with the district conditional on state when each predictor equals to zero.

Statistical Analysis

Data analysis was carried out by using STATA software version 13.0.

Results

Out of the total 174607 women analysed, mostly (87.4%) were in the age group 20-30 years, nearly half (46.5%) with secondary level education followed by 28% with no education. The 2nd and 3rd para women were 51.2%, while 33.3% were of 1st para. In present study, preponderance was of Hindus women (80.7%) and rural (70.6%) and nearly half belonged to OBC caste (45.3%). Out of the total women participants, 51.2% had >4 ANC visits and 83.3% deliveries were assisted by SBA; while nearly one of seven women (14.6%) were either late or not registered for ANC services for the pregnancy. The late or no registration for ANC care was higher in women of higher age, higher order child birth, illiterate, rural population and poorest income group (Table/Fig 1).

The VPC at state level (27.84%) and district levels (7.60%) were substantial which cannot be ignored while estimating the predictors. The application of multilevel model proved a better approach for precise estimates (-2Log L=189334) compared to ordinary logistic (-2Log L=2202689). Compared to women of age 15-19 years, >4 ANC visit in women of age 20-34 years was statistically same in ordinary logistic model (OR=0.95; 95% CI: 0.90-1.01); but in multilevel modelling it was significantly higher (OR=1.09; 95% CI: 1.02-1.17). In ordinary logistic model, >4 ANC visit in ST and other caste category women were statistically higher compared to SC women (OR: 1.24; 95% CI: 1.20-1.29 for ST and OR=1.04; 95% CI: 1.01-1.08 for other caste category). But, in multilevel modelling, it was statistically higher only in women of other caste category (OR=1.11; 95% CI: 1.07-1.16). The vast variation in the estimates between the multilevel and ordinary logistic models for the predictors child birth order, education of the mother and wealth quintile could be seen (Table/Fig 2).

Similarly, (Table/Fig 3) showed variations at state and district level with 39.36% and 8.41%, respectively. Log likelihood values showing multilevel logistic (-2Log L=141148) a better model against ordinary logistic (-2Log L=151978). The ordinary logistic model indicated that the births assisted by SBA were significantly lower in Muslims (OR=0.56; 95% CI: 0.54-0.58) as well as in other religion group (OR=0.84; 95% CI: 0.79-0.90); while in multilevel logistic model, it was significantly lower only in Muslim women (OR=0.71; 95% CI: 0.71-0.77).

The variance partition coefficients for late or no registration for ANC attributed to state and district levels were 12.24% and 7.10%, respectively. Thus, identifying the predictors of late or no registration and the estimates of odds ratio for their different categories; multilevel model will be the robust model. Late or no registration was almost one in seven i.e., 14.6%. The predictors, mother education, child birth order and wealth quintile were major contributor to late or no registration. Compared to illiterate women, the likelihood of late or no registration was lesser by 15%, 28% and 30% in women with primary, secondary and higher education, respectively. While the likelihood of late or no registration was higher by 1.11, 1.35 and 1.69 times in women of child birth order (1st, 2nd, 3rd, 4th, 5th or ≥6, respectively when compared to women of first order. A negative association of wealth quintile with late or no registration was found; higher the wealth quintile, lower was the likelihood of late or no registration. Rest predictors i.e., age of women, religion, caste, place of residence and distance of health facilities also influenced late or no registration but were minor contributors as compared to other parameters (Table/Fig 4).

Discussion

This study first validated the utility of multilevel model compared to the ordinary logistic model on the data of NFHS-IV collected under clustered design. This was validated by -2 Log likelihood values obtained under multilevel and ordinary logistic regression models for the outcomes ANC visits >4 and delivery assisted by SBA as mentioned in the result section. Thereafter, the predictors of late or no registration of pregnancy were identified. Multilevel modelling in hieratical structure of data has the advantage wherein the random effects are specified at each level of analysis. With clustered data, observations from the same cluster are generally more similar than observations from different cluster and using ordinary logistic regression model violate the assumption of independence of all observations (19),(20).

The data set of NFHS-IV used here for late or no registration showed variations associated with state level as 12.24% and at district level as 7.10%. These variations are quite obvious as women living in the same region (cluster) may share similar characteristics like religious believes, access to health care services and socio-economy conditions; so, justifying the findings using ordinary logistic regression is inappropriate (21). Singh PK et al., and Wulandari RD et al., had examined the predictors of full antenatal care and found education has positive influence and higher birth order as barrier on utilisation of antenatal care, which is similar to our findings (4),(5). While Akowuah JA et al., used logistic regression approach on Demographic and Health Survey data of rural Mali and showed much of the area-level influences on the use of Maternal and Child Health (MCH) services (8).

Late or no registration of pregnancy is still a major concern in India which is attributed to low education of women, poverty, ignorance of benefit of MCH services and access of MCH services. Still almost one in seven women either do not get registration or register very late. Studies has pointed that the mothers who are late or not registered for ANC services are more likely to give birth to underweight babies of whom survival is poor (22),(23),(24),(25). In fact, state and district level effects for late or no registration of pregnancy are substantial (VPC 12.24 at state level and 7.10 at district level). The late or no registration of pregnancy was found to be associated with all the considered predictors. However, education, child birth order, wealth quintile, distance to health facility, place of residence were the important. As the level of education and wealth quintile was increasing, the likelihood of late or no registration of pregnancy was decreasing; while likelihood of late or no registration of pregnancy was increasing with increasing birth order. Religion as well as caste also had role to play for late or no registration.

Limitation(s)

Firstly, these predictors at individual and household level can identify the pockets with late or no registration for ANC, but cannot establish the causal association and secondly since the data relates to theme assures being self-reported by mothers with a recall period of upto five years, hence subject to recall bias.

Conclusion

The hieratical structure of data used here demonstrated variation at state and district levels, thereby large variability in the estimates of various categories of predictors in multilevel model compared to ordinary logistic model was seen and more robust was with multilevel model. Late or no registration was more concentrated in low educated, higher order child birth and in poorer wealth quintile income class. These women are about two third from rural areas, therefore a programmatic drive is needed to enhance the timely registration for ANC to bring improved health of mother and new born.
