Statistics in randomized controlled trials (RCT)

2., 3. and 4. November 2022, 9:00 - 12:30 at Lille Auditorium, Domus Medica, Sognsvannsveien 9

Course objectives

This course gives an overview of methodological issues and challenges in the design and statistical analysis of randomized controlled trials. We will discuss practicalities and common issues to keep in mind when planning an RCT. We will focus on the key elements of a well planned RCT, considering different study designs and presenting the most common challenges in the statistical analysis of the results. The topics will be presented based on real examples and cases experienced by the instructors.

The course is divided into three parts:

  1. Introduction and main components of RCTs: structure of RCTs, basic study design, possible biases, blinding, randomization
  2. Hypothesis tests and sample size: different types of tests, different types of outcomes, what to report, sample size calculation and related issues, interim analysis
  3. Different study designs and further challenges in planning RCTs: more study designs (crossover trials, cluster-randomized trials,..), compliance issues, missing data, practical issues in analyzing and reporting results
