Cumulative hazard ratio estimation for adverse events data from two-stage dynamic treatment regimes

open access: yesFrontiers in Applied Mathematics and Statistics
Accurate analysis of adverse events in two-stage dynamic treatment regimes is complicated by the presence of competing risks, such as death, which can preclude the observation of an adverse event and introduce bias into standard survival estimates.
