D. Scharfstein et al., Inference in randomized studies with informative censoring and discrete time-to-event endpoints, BIOMETRICS, 57(2), 2001, pp. 404-413
In this article. we present a method for estimating and comparing the treat
ment-specific distributions of a discrete time-to-event variable from right
-censored data. Our method allows for (1) adjustment for informative censor
ing due to measured prognostic factors for time to event and censoring and
(2) quantification of the sensitivity of the inference to residual dependen
ce between time to event and censoring due to unmeasured factors. We develo
p our approach in the context of a randomized trial for the treatment of ch
ronic schizophrenia. We perform a simulation study to assess the practical
performance of our methodology.
