Some Problems of Multiplicity in Long-Term Intervention Studies

Much has been learned about the design and execution of long-term intervention studies from the experience with the recent major trials1–11 evaluating various platelet suppressing drugs in the secondary prevention of myocardial ischemia or cerebral ischemia. These studies have also served to highlight a number of misconceptions and oversights about statistical analysis and interpretation, particularly as they relate to the multiplicity of questions which, of necessity, must be asked of the data both as they accumulate and at the completion of the study.
