Bibliometric analysis of publications on polycystic ovary syndrome and Turkey's scientific contribution

Amaç. Bibliyometrik çalışmalar, özgün bir konu ile ilgili birikmiş bilimsel verileri inceleyerek, okonu ile ilgili nitel bilimsel performansı değerlendirmek için gerçekleştirilir. Bir ülkenin belli birkonu hakkındaki nitel performansının bibliyometrik analiz açısından yorumlanması, o ülkeninmedikal veri sunumuna katkısının nitel ve nicel olarak değerlendirilmesinde önemli bir yoldur. Buçalışmada, Polikistik Over Sendromu ile ilgili bilimsel yayınların kantitatif analizini yapmayı,ayrıca Türk kurumları ve yazarları tarafından yayınlanarak Science Citation Index Expandedkapsamındaki tıbbi dergilerde yer almış yayınları araştırmayı amaçladık. Yöntemler. Web ofScience yazılımını kullanarak, 1980-2012 yılları arasında polikistik over sendromu alanındayayınlanmış makaleleri retrospektif olarak araştırdık. Bu amaçla Science Citation İndex Expandedkapsamındaki dergilerde yayınlanmış olan makaleler dikkate alındı. Bulgular. 1980 den araştırmatarihine (29 Haziran 2012) kadarki SCI Expanded veri tabanında yapılan Web of Science temelliaraştırmada, polikistik over sendromu ile ilgili 8891 adet İngilizce bilimsel dokümana ulaşıldı.Bunların arasında 2836 tanesi (%31,9) Amerika Birleşik Devletlerinden idi. Bunu İngiltere(%9,75), İtalya (%8,45) ve Türkiye (%5,34)nin takip ettiği saptandı. 1980lerin başında polikistikover sendromu ile ilgili uluslararası bilimsel repertuar göreceli olarak yetersizdi, ancak,1990lardan sonra yayın sayısında uluslararası bir artış olduğu gözlemlendi. Diğer taraftan,Türkiye kökenli yayınlar 1990lardan sonra görülmeye başlandı. Polikistik over sendromuaraştırmalarının uluslararası repertuarına Türkiyenin katkısı 2000lerden itibaren artış gösterdi.Yayın sayısı açısından yazarların sıralamasına bakıldığında; R. Azziz birinci olup, RS. Legro ve S.Franks onu takip etti. Türk yazarlar arasında da ilk üç sırada BO. Yıldız, F. Kelestimur ve H.Yaralının yer aldığı saptandı. Polikistik over sendromu ile ilgili makaleleri yayınlayan dergilerarasında en çok tercih edilenin Fertility Sterility olduğu saptandı. Sonuç. Polikistik over sendromualanındaki uluslararası bilimsel yayınlarda, 1990lardan itibaren belirgin artış görülmeye başlandı.Türkiye, bu alandaki bilimsel repertuara yaptığı katkı açısından önemli bir yere sahiptir. Bu katkıson 10 yılda düzenli bir şekilde artış göstermektedir.

Polikistik over sendromu konulu yayınların ve Türkiye 'nin bilimsel katkısının bibliyometrik analizi

Aim. Bibliometric studies can be used to evaluate the quantitative scientific performance on aspecific topic via evaluating the accumulation of scientific data. Interpreting quantitativeperformance of a country with respect to bibliometric analyses is an important way to assess thequality and quantity of that country s contribution to the dissemination of medical evidences abouta topic. In this study, we aimed to make a quantitative analysis of the scientific publications relatedto Polycystic Ovary Syndrome and also to investigate publications originating from Turkishinstitutions and authors, which are published in Science Citation Index Expanded covered medicaljournals. Method. We retrospectively searched papers published in the field of polycystic ovarysyndrome between 1980 and 2012 by using the Web of Science software. Papers that werepublished in Science Citation Index Expanded covered journals were taken into account. Results.Web of Science based search on the field of Polycystic Ovary Syndrome through the database ofScience Citation Index Expanded from 1980 to the date of the study (June 29, 2012), revealed8891 English scientific documents. Among these, 2836 (31.9%) were from United States ofAmerica, followed by England (9.75%), Italy (8.45%), Turkey (5.34%). The internationalscientific repertory on polycystic ovary syndrome was relatively poor in the beginning of 1980s,however; we observed an international acceleration with respect to the publication number after1990s. Publications from Turkey on the other hand showed up only after 1990s. Turkey scontribution to international repertory of polycystic ovary syndrome research speeded up after2000s. When the ranking of the authors with respect to the number of publications was evaluated,Azziz R was found to be the first, followed by Legro RS, and Franks S. Yildiz BO, Kelestimur F,and Yarali H were the first three among Turkish authors. Fertility and Sterility was found to be themost preferred journal publishing papers about polycystic ovary syndrome. Conclusion.International scientific publications on the field of PCOS started to increase notably after 1990s.Turkey has a prominent place with respect to its contribution to the scientific repertory on thefield. This contribution has been steadily increasing during the last decade.
