Popis: In clinical trials data of individuals are collected, who are subjected to different treatments under controlled conditions. These studies investigate differences between interventions, and their results--provide the basis for clinical decision making in individuals or for policy decisions concerning entire patient populations. This requires reliable results. How confident a result of the study actually is, is illustrated by using various statistical parameters: p-value or confidence interval. What these parameters are and how to interpret them, is the objective of this article.
