• Knowledge of applied statistical methods used in epidemiological studies is assumed (e.g. epidemiological study designs, multiple logistic regression). No prior knowledge of genetics, instrumental variable techniques, or Mendelian randomization is necessary.

Computing practicals:

  • Participants will gain most from the practicals if they have a working knowledge of either R or Stata, and bring a laptop with R or Stata loaded. For others, it is possible to share the practical sessions with those participants who have this experience.

Course objectives:

    After the course, participants should have sufficient knowledge to undertake their own Mendelian randomization analyses, to understand the assumptions on which causal inferences are based, and to critically appraise published studies using Mendelian randomization.
