Meta-Analysis Steps and Reporting

Abstract

Evidence based medicine is a medical decision making approach using the best available medical evidence. For this, the research question should be clearly defined, the evidence should be investigated, the evidences should be assessed, the medical decisions must be made and implemented and the results of the implementation should be observed. Meta-analysis and systematic review are at the top of the evidence based-pyramid at evidence based medicine. Meta-analysis is an original article that it is the synthesis of a large number of researches to reach a large number of data, provides more reliable information about the subject being searched. When the meta-analysis is prepared; the research question is determined, the literature is searched and appropriate studies are selected, the selected researches are coded, the effect size is calculated, the data are analyzed again according to the effect sizes and meta-analysis is written respectively. The PRISMA Protocol is often used in conducting meta-analysis. This review summarizes steps for evidence based medicine, steps for conducting meta-analysis, the PRISMA Checklist and the PRISMA Flow Diagram which are translated into Turkish. This review is belived to be a valuable contribution to Turkish scientist, especially in planning to conduct a meta-analysis.


Kanıta dayalı tıp, elde bulunan en iyi tıbbi kanıtları kullanarak tıbbi karar verme yaklaşımıdır. Bu amaçla araştırma sorusu net olarak belirlenmeli, kanıtlar araştırılmalı, belirlenen kanıtlar değerlendirilmeli, tıbbi karar verilmeli ve uygulanmalı, uygulamanın sonuçları gözlenmelidir. Kanıta dayalı tıpta, kanıt piramidinin en üst basamağında meta-analiz ve sistematik derlemeler yer almaktadır. Meta-analiz, çok sayıda araştırmayı sentezleyerek geniş veri sayısına ulaşmayı ve araştırılan konu hakkında daha objektif bilgiler edinilmesini sağlayan bir orijinal araştırma türüdür. Meta-analiz hazırlanırken, sırasıyla araştırma sorusu belirlenir; literatür taraması yapılarak uygun araştırmalar seçilir, seçilen araştırmalar kodlanır; etki büyüklüğü hesaplanır, etki büyüklüklerine göre veriler tekrar analiz edilir ve meta-analiz yazılır. Meta-analiz yazım aşamasında sıklıkla PRISMA Protokolü’nden yararlanılmaktadır. Bu derlemede, kanıta dayalı tıp basamakları, meta-analiz yazım basamakları özetlenmiş; PRISMA Kontrol Listesi ve PRISMA Akış Şemasının Türkçe çevirilerine yer verilmiştir. Bu araştırmanın özellikle meta-analiz yapma hazırlığında olan araştırmacılara katkısı olabileceği düşünülmektedir.
