Query: Individualized Treatment Effects with Censored Data via Fully
  Nonparametric Bayesian Accelerated Failure Time Models   Individuals often respond differently to identical treatments, and
characterizing such variability in treatment response is an important aim in
the practice of personalized medicine. In this article, we describe a
non-parametric accelerated failure time model that can be used to analyze
heterogeneous treatment effects (HTE) when patient outcomes are time-to-event.
By utilizing Bayesian additive regression trees and a mean-constrained
Dirichlet process mixture model, our approach offers a flexible model for the
regression function while placing few restrictions on the baseline hazard. Our
non-parametric method leads to natural estimates of individual treatment effect
and has the flexibility to address many major goals of HTE assessment.
Moreover, our method requires little user input in terms of tuning parameter
selection or subgroup specification. We illustrate the merits of our proposed
approach with a detailed analysis of two large clinical trials for the
prevention and treatment of congestive heart failure using an
angiotensin-converting enzyme inhibitor. The analysis revealed considerable
evidence for the presence of HTE in both trials as demonstrated by substantial
estimated variation in treatment effect and by high proportions of patients
exhibiting strong evidence of having treatment effects which differ from the
overall treatment effect.
