Abstract

The results of randomized clinical studies are important in evaluation of drugs’ or medical procedures’ efficacy. Statistical analyses are meaningful in publications and conference presentations. This paper discusses the role and value of selected statistical methods. It is clear that in clinical studies patients and time to event (recognized as end study point) are essential. According to that the question arises — do all these statistical analyses are important or do they play only a role in drug promotion.
