Background: Thyroid Research and Practice (TRP) has been in existence since 2004 and since then it has been working for dissemination of knowledge and research in the field of thyroidology. This work was aimed at performing bibliometric analysis of TRP. Materials and Methods: The publications of year 2006-13 of TRP were analysed. Total number of articles published, type of articles, their authorship, and the coverage of various subspecialties was studied. The publications were also classified as being of Indian or foreign origin and from academic or non-academic institutions depending upon the institution of first author. Results and Conclusions: A total of 23 main issues and 1 supplementary issue were published in TRP in years 2006-13, including a total of 210 publications. Taking collectively, original articles were published in majority. There was a widespread coverage of all subspecialities of thyroidolgy, but maximum number of articles dealt with clinical thyroidology. Publications were largely originating from academic institutions. Although maximum number of articles were from India but the publications from other countries are also on an increase. Articles from all parts of the country have been published in TRP, but Kerala has contributed maximally.

  Introduction Top

Thyroidology is a mature specialty of medical science, which straddles both paraclinical subjects such as pathology and nuclear medicine, as well as clinical disciplines such as medicine and surgery . Thyroid Research and Practice (TRP) is one of the oldest journals exclusively devoted to thyroidology. The official journal of the Indian Thyroid Society, TRP has functioned as a platform for dissemination of knowledge and research in this field since 2004.

Bibliometry is a means of objectively assessing the amount and spectrum of papers published in a particular book or journal. This helps in quantifying the contribution made by the publication, determining its impact, and assessing whether or not it is doing justice to its chosen subject. This analysis also helps in framing future editorial decisions and policies, and provides a reader-friendly assessment of the publication. Bibliometry also serves as a bench marking tool, with which other publications, or future issues or editions of the same publication, can be compared. In general, bibliometry serves as a scientific tool to help further the cause of science.

Bibliometric analysis has been conducted for Indian journals in the recent past. [1],[2],[3] Thyroidology has maintained a place of pride in both national competitions and journals. [3],[4] As TRP completes a decade of existence, it is but appropriate that a similar analysis be performed and presented for this prestigious journal.

  Materials and Methods Top

TRP issues of the last 8 years (2006 to 2013), which were available online, were taken for analyzing the publication trends in this journal. The data was derived from the website of the journal which gives link to the previous issues. Missing information was collected from the editor of the journal.

The articles published were analysed for the type of the articles (editorial, review article, original article, case report, letter to the editor, abstracts, and others). Certain types of articles which appear infrequently were clubbed with larger categories, for ease of analysis. Mini reviews, basic science reviews and commentary were grouped with review articles. Presidential orations were included with editorials while short articles were clubbed with letter to the editor.

The categorization of articles according to the subspecialties was made, and modified, in consultation with the editor. The articles were divided into five major groups, namely clinical thyroidology, investigational thyroidology, thyroid interface with endocrine systems, thyroid interface with non-endocrine systems and thyroid interface with allied non-clinical specialties. In case of conflict, e.g., "autoimmunity in pregnancy", the first mentioned phrase, viz., autoimmunity, in this case, was chosen to decide classification. Divergent opinion was resolved by consensus between authors. Abstracts and other articles were not classified according to subspeciality.

The articles were later categorized as being of Indian or foreign origin, and from academic or non-academic institutions depending upon the institution of the first author. The top 10 states of the country which contributed maximally toward the journal were also assessed. For this classification, abstracts were not included.

  Results Top

Over the past 8 years, Thyroid Research and Practice journal published 8 volumes, comprising of 23 main issues and 1 supplementary issue. These included a total of 210 publications, comprising of 24 editorials, 30 review articles, 45 original articles, 29 abstracts, 40 case reports, 12 letters to the editor and 30 other articles [Table 1].

The total number of publications has been increasing continuously, especially over the last 3 years, after a dip seen in the years 2009 and 2010 [Figure 1]. Among all the articles, original articles and case reports were published maximally [Table 1] and [Figure 2].

The publications of TRP covered every subspeciality of thyroidology. [Table 2] and [Figure 3] Although clinical thyroidology received maximum coverage (44%), coverage of rest of the thyroid subspecialities was almost balanced. Medical thyroidology received maximum coverage (13.9%), followed by oncology (10.59%) and obstetric (7.28%) aspects of thyroidology. Within endocrinology, the thyroid interface with obesity/metabolic syndrome/cardiovascular system (7.94%) was the most prominent, while among the basic and paraclinical sciences, public health received maximal coverage (8.60%). Publications from academic institutes (70. 71%) exceeded those from non-academic institutes (29.28%) [Table 3].

Although most publications were from India, other countries like USA, UK, Thailand, Australia, Nigeria, Iran also contributed their share toward making this journal an international one [Table 4].

All parts of India-north, east, west and south, have worked to make TRP a success. Amongst the Indian states, Kerala contributed maximally toward this journal, especially in its initial years. It was followed by Haryana, Karnataka, and Delhi. Of the 65 article written by Kerala-based authors, however, 27 belong to the category of Thyroid Watch and Thyroid Images [Table 5] and [Figure 4].

  Discussion Top

This bibliometric study has tried to assess and analyse the publication trends of TRP. The journal is a very vibrant journal, with growing popularity and an open editorial policy. Its popularity is reflected in the large number of publications of TRP, which has been increasing, particularly in last 3 years. It is also supported by the high frequency of hits noticed on the website.

The open editorial policy is obvious from the focus given to original research articles, the inclusion of editorials from across the country, and the balanced coverage of all sub-specialties of thyroidology. Both clinical and non-clinical aspects of thyroidology have been covered, but more attention has been given to clinical thyroidology, representing the major concerns of practising thyroidologists in India. Investigative modalities and thyroid interface with endocrine and non-endocrine systems have also been covered well.

Although there is overall more representation of academic sector in TRP, but contribution of non-academic sector toward the journal is on an increase. While the majority of publications in TRP are from India, other countries have also started showing up in the journal, suggestive of growing popularity of the journal. In TRP, there are publications from all parts of the country. Kerala seems to have contributed maximally toward the journal, especially in its earlier years, but all states are contributing now. Twenty-seven out of 30 articles belonging to thyroid watch and thyroid images category are from Kerala. The state wise distribution of the remaining articles is comparatively much more balanced. This finding is in contrast to that reported by earlier endocrine bibliometrists. [3]

  Conclusions Top

This bibliometric analysis highlights not only the fact that thyroidology is an all inclusive specialty, but also that TRP is doing justice to it. It is hoped that this analysis will serve as a bench mark for future studies, and will also help inform editorial policy, so as to make TRP an even more representative, more effective, and more efficient, face of Indian thyroidology.
