Advanced issues in the design and conduct of randomized clinical trials: the bigger the better?
Stat Med.
.
Abstract
Large trials provide more precise estimates of treatment effects than small trial (how good is the treatment?) and they may allow a few sensible and pre-defined sub-group analyses (for whom does the treatment work best?). But large trials will not get done unless they are simple and as part of normal clinical practice as possible.
