Abstract
Designing an observational epidemiological study is a challenging task. It requires detailed consideration of aspects such as measurement and definition of exposure and outcome variables, potential confounding variables, biological plausibility of the studied association, or causality. These aspects, together with data availability, impact the choice of applied study design. This chapter gives an overview of these aspects, with a focus on medication use as the exposure variable.
