Survivor average causal effects for continuous time: a principal stratification approach to causal inference with semicompeting risks

Authors: Leah Comment, Fabrizia Mealli, Sebastien Haneuse, Corwin Zigler

arXiv

In semicompeting risks problems, nonterminal time-to-event outcomes such as time to hospital readmission are subject to truncation by death. These settings are often modeled with illness-death models...
