Mapping of Celiac Disease Research Literature: A Scientometric Approach

The study aims to evaluate the celiac disease research publications in the Web of Science database from the years 2015 to 2018. The keyword used the term "Celiac Disease" from the Web of Science database collects the records. A total of 4147 records were collected from this study of Celiac disease. The highest productive year is 2017 with 1062 records (25.61%) and the last position of papers was published 1016(24.50%) in the year is 2016. The table provides the value of the average RGR of publications, which decreased from 6.93537 in 2015 to -0.01997 in 2018. At the same time, the value of doubling time (DT) of publications increased from 0.099923 (2015) to 34.6983 (2018). It has shown that the degree of collaboration range from zero to 0.95. The most prolific author Lebwohl B occupied in first position 107(2.58%) records. The most productive country USA placed in the topmost position with 1149(27.71%) records. The authorship pattern of celiac disease research this table notes that the majority of the articles were contributed by four authors 549(13.24%). These three authors were contributed 538(12.97%) second position of papers in this study. The first position of the journal is Gastroenterology published records with 260(6.27%). The language-wise distributions of published records in Celiac disease research in this present study. The most productive language is English with 4032(97.23%), and the last Original Research Article Clarance and Raja; JPRI, 33(49A): 150-160, 2021; Article no.JPRI.76059 151 productivity language is Icelandic with 1(0.02%) publications. The Study concludes that Celiac Disease Research lags in this research, so come forward with financial institutions to encourage researchers and scientists to develop celiac research.


INTRODUCTION
Scientometric is a branch of science, "Science of Science". Scientometric is a scientific discipline that makes reproductive measurements of scientific activity. Nowadays, science is one of the truly interdisciplinary research fields that has expanded to almost all scientific disciplines [1]. In this celiac disease study, the author discusses, analyzes the study and uses a variety of scientific methodology tools and technologies, such as the degree of collaboration for the paper. Among them, Celiac disease is one of the most common autoimmune diseases in the world. This disease is affecting nearly 1% of the people in the United States. Celiac disease is called celiac sprue or gluten-sensitive enteropathy is a digestive. These diseases damage that introduces to the small intestine after foods with gluten are eaten. Gluten is a form of protein was found in some grains. Celiac disease is improved at any time in life; from affect adulthood, and more women than men being diagnosed. Celiac disease is many of the symptoms is created, but one of the most difficult of diagnosis problems. These diseases trigger some type of autoimmune disease. The simple treatment for the celiac disease patient is only a lifelong gluten-free diet taking of our life [2]. Scientometric analysis of literature provides the research in the field is concerned. The present study analyzes the publication trends of Celiac Disease research is applying Scientometric indicators.

REVIEW OF LITERATURE
Previous studies identified that there is related research has been reported in many disciplines. Antony [4] examined the research undertaken in Indian medical colleges and concluded that the high position of the 88 Indian medical colleges receiving research grants from ICMR did not produce any research paper in 1991. This paper is only 10% of the projects funded to Indian medical colleges on the publications in indexed journals. Bala and Singh [5] in this study discussed Scientometric as the Science of measuring and analyzing Science. This study reveals that a single author contributed 18 (5.7%) while Multi authors2 provided the rest of 162 (51.3%) articles. Bansal [6] Consist of this study is an analysis of 14317 world papers in celiac disease research. This study data was retrieved from the Scopus database for the period 2005-14. The celiac disease research has an annual average growth rate of 5.20%. This study using the citation impact factor is 12.53. The top 15 productive countries with the largest share of the U.S.A were 21.40%. The most productive keyword is gluten-free diet was 18.47% used in this study. Bhardwaj [7] conducted a study on bibliometric analysis on celiac disease research during 2001-2012. Celiac disease is celiac sprue or glutensensitive enteropathy is an autoimmune disorder. The data for the study were collected from Scopus online database. The total records for 14356 papers were published during the period. The study uses some parameters such as type of publications in celiac disease research, the context of different subjects, different population groups, etc. During the study period 2001-2012, a total of 14356 records and 178133 citations received the publications were transferred to MS Excel 2010.

Research Output on Celiac Disease Research
It was found that a total of 4147 papers were published during 2015-2018, is celiac research. Table 1    This table shows that the authorship pattern of celiac disease research this table notes that the majority of the articles are contributed by four authors 549(13.24%). These three authors are contributed 538(12.97%) second position of papers in this study. Five authors and six authors contributed papers occupying third and fourth in the order 490(11.82%) and 461(11.12%) respectively. More than ten authors occupy the fifth position with 441(10.63%), and two authors occupy the sixth position was 431(10.39%). And balance authors followed by the next position are respectively.    The country-wise distribution of celiac disease research output is given in Table 6. The USA placed in the topmost position with 1149(27.71%) records and Italy in the second position with 660(15.92%). The UK is in the third position with 314(7.57%), and other country publications are as follows.       Table 10 shows that the language wise distributions of published records in Celiac disease research in this present study. The most productive language is English with 4032(97.23%), and the last productive language is Icelandic with 1(0.02%).

CONCLUSION
This study revealed that 4147 papers had been published on Celiac Disease Research on 1123Journals. It shows that from 2015 to 2018, the highest numbers of publications 1062(25.61%) were in 2017. Celiac disease research is the degree of collaboration range from zero to 0.95. "Journal of Gastroenterology", published records with 260(6.27%). It is noted that Unknown ranks first position in order by contributing 269 publications. Articles cover the most preferred type is 2514(60.62%). The most productive language is English with 4032(97.23%), and the last productive language is Icelandic with 1(0.02%). The highest articles were published in the year 2017 and the lowest in the year 2016. Celiac Disease Research lags in this research, so come forward with financial institutions to encourage researchers and scientists to develop celiac research.
