1. INTRODUCTION
Indian Journal of Pediatrics
The Indian Journal of Pediatrics1 popularly known as IJP is one of the premier medical
journal in India, founded in the year 1933. IJP is a monthly Peer-Reviewed Pediatric journal. It
has an excellent track record of regular publication for past 87 years and having a magnificent
readership. It is published by Dr. K. C. Chaudhuri Foundation Trust. The journal publishes peer
reviewed scientific articles and is extremely popular amongst its readers. For practicing
pediatricians, the journal serves as an important source of updating themselves in the state of art
practice of medicine. Since it is one of the key journal with a wide spread reach to pediatricians,
various pharmaceutical companies find the journal as an appropriate medium to communicate
with doctors. It brings to its readers the latest advances in the Pediatric World. It is indexed
in “Medline/PubMed, Science Citation Index Expanded (SciSearch), SCOPUS, EMBASE,
Google Scholar, Academic OneFile, BIOSIS, CNKI, Current Contents/Clinical Medicine,
EBSCO Biomedical Reference Collection, EBSCO CINAHL, Expanded Academic, Health
Reference Center Academic, Indian Science Abstracts, MedInd, OCLC, PASCAL, SCImago,
Summon by ProQuest”.
Bibliometrics
Bibliometrics is the application of mathematical and statistical methods to publications.
Bibliometrics is often used to assess scientific research through quantitative studies on research
publications. The term was coined by Alan Pritchard (1969)2 in his 1969 paper entitled
“Statistical Bibliography or Bibliometrics” in which he defined the term as “the application of
mathematics and statistical methods to books and other media of communication”.
2. REVIEW OF LITERATURE
The review of related literature is a significant component in any research investigations.
It enables to understand the research interest, pattern and impact of research productivity in the
field of knowledge. Recently many bibliometric/scientometric studies on single journals have
been carried out.
Patil (2010)3 studied the articles published in Herald of Library Science for authorship
pattern, degree of collaboration and geographical distribution of publications. The study found
that the majority of publications were single authored.
Rajendran, Jeyshankar and Elango (2011)4 carried out scientometric analysis of 633
research articles published in Journal of Scientific and Industrial Research during the period
2005- 2009 and the revealed that the author productivity is 0.34 and dominated by the Indian
authors.
Aswathy, S and Gopikuttan, A (2012)5 studied the bibliometric analysis of Journal of
Spacecrafts and Rockets during the period 2006-2010. The major finding of the study is that the
Universities are the most productive sector and that the most productive country is USA.
Das and Pal (2012)6 studied 199 peer reviewed articles published in "Sankhya - the
Indian Journal of Statistics during the period 2003-2007. It analyzed the authorship pattern,
collaboration trend among authors, etc. among the publications.
Das (2013)7 analyzed 239 research outputs published in the inaugural five volumes of
Journal of Informetrics (JOI). The Findings revealed that publications doubles over the study
period as there was considerable increase of publications over the period of time. The findings
further reveals that (30%) of the total publications were single authored contributions and
collaborated research work dominated the area of study with an average authorship of 2.28
authors per publications.
Rekha, Prabhakar and Mallika (2014)8 studied the research outputs from the Journal of
Scientific and Industrial Research during the period 2004-2013. The study reveals that there are
1297 publications during the period, multi authored contribution outnumbered single authored
publications.
Nageswara Rao, K., et al (2014)9 studied the bibliometric analysis of the Journal of
Propulsion and Power for the period 1983-2013. The study finds that the highest numbers of
articles were produced during the year 1992 with 194 and the lowest in the year 1987 with 81
articles. Out of the total 4047 articles produced, 1330 articles were produced by two authors and
1098 were produced by three authors. It also finds that Purdue University has contributed the
highest number of 163 articles. It also found that Fleeter, S from Purdue University has
contributed the highest number of 54 articles.
Malathy, S and Kantha, P. (2015)10 studied the bibliometric analysis of the Journal of
Spacecraft Technology during 1991-2012. The study provides the insight and development of the
journal towards excellence.
Sujatha and Padmini (2015)11 studied the bibliometric analysis of the journal of IEEE
Transactions on Antennas and Propagation from 2010-2014. The degree of collaboration ranges
between 0.92 to 0.96 and its average value is found to be 0.94. Most of the contributions were
contributed from USA.
Chaman Sab, M and Dharani Kumar P (2016)12 has done citation analysis of annals of
library and information studies during the period 2007-2010. The study indicates that the 4
volumes have 2562 citations appended to the 140 articles. The average number of citations per
contribution is 18.3. The study observed that the journal articles are the preferred cited sources
with the highest percentage of 1811(70.68%).
Zeleznik, Vosner and Kokol (2017)13 in their study pointed out a positive trend in
literature production, although recently, the number of articles published in Journal of Advanced
Nursing has slightly decreased. The study further revealed that the most productive institutions
are from the United Kingdom.
Tsay and Li (2017)14 did a bibliometric analysis of the journal literature on women’s
studies. The results found that most of the document types in the area of women’s studies are in
the form of research articles, review articles and book reviews. The United States of America
and the United Kingdom contribute the largest number of articles. One hundred and seventeen
core journals containing 33% of the women’s studies journal articles have been identified
through the application of Bradford’s law on journal distribution.
Vimlesh Patel (2018)15 studied the Scientometric mapping of papers published in the
Journal of Computer Science and Technology during the period 2012 to 2016. The study
revealed that the researchers in the field preferred collaborated research work.
Swarnamugi, V., Santhi, J and Loganayaki, R (2019)16 studied the citation analysis of the

the journal commands great repute in its field and attracts articles pertaining to the high profile of
research.
3. METHODOLOGY
The study aims to analyze the publications in Indian Journal of Pediatrics. Scopus
database was used to retrieve the data with a time span of 83 years from 1936 to 2018. Even
though the journal founded in the year 1933 at the time of downloading the data, it was available
from the year 1936 only. We have downloaded only the data of citable documents like Article,
Conference Paper and Review during the study period. The common Bibliometric/Scientometric
Indicators like Ratio of Growth (RoG), Compound Annual Growth Rate (CAGR), Degree of
Collaboration (DC), Collaboration Index (CI), Citation per Paper (CPP) and Cited and Uncited
Ratio of the publications were analyzed in the study. For analysis and preparing tables SPSS and
Excel software were used in the study. The following search string was used to download the
data:
(SRCTITLE("indian Journal of Pediatrics") AND PUBYEAR < 2019 AND ( LIMIT-TO (
DOCTYPE,"ar" ) OR LIMIT-TO ( DOCTYPE,"re" ) OR LIMIT-TO ( DOCTYPE,"cp" ) ) )
4. OBJECTIVES OF THE STUDY
• To study the yearly distribution of publication, Ratio of Growth and Compound Annual
Growth Rate of publications
• To study the Authorship pattern by using the parameters like Degree of Collaboration
(DC), Collaboration Index (CI)
• To study the Citation Analysis on publications like Ratio of Growth of Citation, Citations
per paper, Cited and Uncited ratio
• To find out the highly cited publications
• To find out the Top 20 authors and their ranking on total publications, cited rank, uncited
rank and uncited ratio rank.
• To identify the most preferred bibliographic form of documents for publishing research
outputs
• To find out the geographical distribution of publications during the study period
• To find out the major contributing Institutions to the journal.
5. DATA ANALYSIS AND RESULTS
5.1 Yearly Distribution and Growth of Publications in Indian Journal of Pediatrics
There are two common measurements to study the yearly growth of publications in
bibliometric study. Yearwise growth ratio of publications (RoG) is calculated by using the prior
year publications as a base for expressing percentage change from one year to the next
consecutive year. (Ratio of Growth = Number of Publications of Present Year/Number of
Publications of Prior Year.) The other measurement is Compound Annual Growth Rate (CAGR)
which can be calculated by using the formula:

5.2 Authorship Pattern in Indian Journal of Pediatrics
Table 2 represents the authorship pattern of the published literature in the Indian Journal
of Pediatrics. The publications during the study period 1936 – 2018 were categorized as single
authored publications and multi authored publications viz., two authors, three authors, four
authors and five and above authors (the publications which contributed by five and more than
five authors are categorized as a single entity). The average number of authors per publications
was calculated by total number of authors/total number of publications and average number of
publications per author was calculated by total number of publications/total number of authors
and the same has been tabulated.

It is observed from the above table that there are 2380 (27.3%) single authored
publications contribute to the published literature. The co-authored productivity comprises of
1868 (21.3%) two authored publications followed by 1639 (18.8%) five and above authors
contributions, 1570 (18%) three authored publications and the least number of contributions by
the four authors category with 1275 (14.6%) publications. We can further observe that the single
authored contributions are 27.3% of the total published literature while the co-authored
publications contributes to the remaining 72.7% of the published literature shows the dominance
of co-authored publications over the single authored contributions. It clearly shows the
researchers contributed to this journal are more interested in collaborative research work rather
than the solo one. The average number of authors per publication is 2.76 and the average number
of publications per author is 0.36. Fig. 5 shows the Authorship pattern of the published literature.

Table 3 represents the yearly distribution of Authorship pattern of the published literature
in the Indian Journal of Pediatrics. In the bibliometric study, the authorship collaboration in
publications during a specific time period can be calculated using the Degree of Collaboration
(DC) indicator (Subramanyam, 1983)17. The Degree of Collaboration (DC) among authors is the
ratio of the number of collaborative publications versus the total number of publications
published in a discipline during certain period of time and the same can be calculated using the
formula DC = Nm/(Nm+Ns); where, Nm = Number of multiple authors publications during a
specific period in a discipline and Ns= Number of single authored publications in the discipline
during the given period of time. The Collaborative Index (CI) (Lawani, 1986)18 is interpreted as
mean number of authors per paper. CI can be calculated using the following formula CI =
Number of authors in the multi-authored publications/ Number of multi authored publications.

From the above table it is observed that the Degree of Collaboration (DC) ranged
between zero and 0.98 and the average value of DC stands at 0.73 during the study period. The
Degree of collaboration stands between zero and 0.5 till the year 1967 with minimal fluctuations
in between shows that the single authored publications shows dominance over co-authored
publications during the period. After the year 1967 and till the end of the study period, the co-
authored publications shows dominance over single authored publications. The Collaboration
Index (CI) ranged between 1 and 3.77 with an average value of 2.76. The figure 6 represents the
Degree of Collaboration (DC) and Collaboration Index (CI) of the published literature in the
Journal of Indian Pediatrics. It is clearly observed that both DC and CI show increase in trend
over the period of time and dominance of coauthored research work and increase in collaboration
among authors.

5.3 Citation Analysis of Indian Journal of Pediatrics
5.3.1 Cited Publications
Citation is an important factor for any research output, which is being used to measure its
quality. The number of citations to a particular research works shows the impact among the
scientific community like authors/scientists/researchers. Similar to the publications Growth ratio,
the citations growth ratio can also calculated by using the citations yielded by the prior year
publications as a base for expressing change from one year to the citations yielded by the
publications of the next consecutive year. Citations per paper (CPP) can be calculated by using
the formula: CPP = Total number of Citations for a Country or an Institution/Total number of
Quality Publications.

year 2007. It is further observed that the citations growth ratio mostly remained between 0.5 and
2.0 throughout the study period with few minimal exceptions. It attained its peak value of 4.5 in
the year 1954. Figure 7 represents the yearly distribution of growth ratios of citations. It shows
that the ratio of growth of citations is in fluctuated trend with lot of rise and fall during the study
period and not follows a steady growth pattern. Similar to the citations growth ratios the
Citations per paper also shows a fluctuated trend over the period of time. It shows a remarkable
increase in trend between the period 1985 and 2005 even though there was some fall in between
period of time in CPP during the period. The CPP trend goes downfall in recent years that is
from the year 2009. The figure 8 shows citations received by the publications, its growth ratio
and citation per paper in a single graphical representation. Overall two third of the total
productivity were received citations shows that the journal publish quality research productivity
in the area of Pediatrics.

contributions made to the journal by the researchers from all over the World during the period
1936 to 2018. A total number of 8732 publications were reported during the study period to the
Journal. The growth ratio of the research productivity shows a fluctuated trend over the period of
time. The yearly cumulative growth of publications shows an exponential trend. The average
number of authors per publication is 2.76 and the average number of publications per author is
0.36. From the beginning of the study period to 1967, single authored contribution showed some
dominance over the coauthored publications. But beyond that period, the Coauthored
publications outnumbered single authored contributions. The average Degree of Collaboration
during the study period is 0.73. Nearly two third of the total publications got cited during the
study period. Out of the 8732 total publications 5825 publications got cited and yielded 40285
citations with an average of 6.92 citations per cited publications. Even though one third of the
total publications are yet to receive its citations hopes are there for them to get cited due to the
