ABSTRACT

Randomized controlled trials (RCTs) are considered the highest level of evidence for efcacy in healthcare; carefully planned and well-executed RCTs give us the best estimates of treatment effect and RCTs frequently in¤uence clinical decision making (Mulrow et al., 1998; Sackett et al., 1998; Altman et al., 2001). But, trials that lack methodological rigor may cause over-or underestimations of treatment effect sizes
