4  cards
4. Core elements of the ‘classic’ intervention study design

0  cards
5. Intervention strategies
informed consent procedure, randomization, prestratification, blinding, dealing with protocol deviations (drop-outs, non-compliance, missing values), registration of (serious) adverse events.
0  cards
6. Alternative intervention study designs
