Popis: | Results of clinical trials are presented in different expressions of risks: baseline risk, relative risk (RR), relative risk reduction (RRR), absolute risk reduction (ARR), or risk difference (RD). In this article of our series about the basics of evidence-based medicine we show how results of clinical trials are calculated based on the 2 x 2-table. The 2 x 2-table usually contains all information needed to calculate the main study results. Adequate interpretation of the results/treatment effects is the basis for evidence-based advices in pharmaceutical practice. |
