In a case-control study, risk set sampling will identify the controls from a group of people who are ‘at risk’ at the index date of the case. This concept covers the sampling with replacement, so that a control could potentially be used multiple times for different cases. A sampled risk set of size mis a subset of the risk set that contains the case and m 1 sampled controls. So, for instance, for 1:1 simple nested case-control sampling, each sampled risk set consists of the case and one control randomly sampled from all the controls in the … The theory of risk set sampling provides a means to develop a wide variety of sampling schemes for case-crossover studies.
