In drug eluting stent clinical trials, Repeat Revascularization is often defined as an important safety outcome. However the revascularization procedure itself is cosidered a treatment. The usual approach for the estimation of treatment effect on mortality and morbidity may be biased, especially when many patients receive repeat revascularization due to disease progression after randomized for the original revascularization treatment. In this presentation, the different statistical methods on how to address the causal effect as well as real-life examples will be provided.
