| الوصف: | Background & Aim: It is important that clinicians understand statistical methods into their own research and correctly apply in their research. The main objective of this study is to explore the study designs, statistical methods used and the issue of inaccuracy and inappropriate usage of statistical methods in the research publications of the specialty of general medicine as evidenced by five selected journals over a 10-year period and improvements thereof. Methods & Materials: Originally published articles were reviewed of the journals of specialty of general medicines for the above-defined objective (list of journals: Indian Journal of Medical Research, Indian Journal of Critical Care, Indian Journal of Nephrology, Journal of the Association of Physicians of India, and New England Journal of Medicine were reviewed). Qualitative data represented by percentage, Z-test of proportion applied at 95% level of significance. Results: The usage of some statistical methods in 2003 was 61.54% which increased to 79.26% by 2013. Only 2.19% research article had mentioned the concept of study design in 2003 which increased to 10.56% by 2013. There was a greater usage of statistical concepts and methods such as parametric and nonparametric tests, regression, survival analysis in 2013 as compared to 2003. There was a significant improvement observed in the usage of statistical software over a 10-year period. A common error observed was the usage of standard error instead of standard deviation to present the data and we found that there was a vast improvement in the use of advanced statistical methods over the decade. Conclusion: This study highlights the increasing importance of medical statistics in the research publications pertaining to the specialty of general medicine over time so that the inferences drawn from these studies are actually representative of the population that they represent and are valid and reliable. These concepts are of paramount importance while physicians read these articles and try to adopt their recommendations. |
