Sample size calculations based on a difference in medians for positively skewed outcomes in health care studies
BACKGROUND: In healthcare research, outcomes with skewed probability distributions are common. Sample size calculations for such outcomes are typically based on estimates on a transformed scale (e.g. log) which may sometimes be difficult to obtain. In contrast, estimates of median and variance on th...
