title: Evaluation of research studies. Part I: Randomized trials.
abstract: Clinical practice is often based on the results of research. Critical evaluation of research studies is important if appropriate conclusions are to be drawn. In this series of columns, we review principles of research methodology and statistical analysis. Our intent is to assist certified nurse-midwives in understanding the relative merits of the research they read and use. This article, the first of the series, will review issues pertinent to randomized clinical trials.
