2007 journal article
"Smooth" semiparametric regression analysis for arbitrarily censored time-to-event data
BIOMETRICS, 64(2), 567–576.
author keywords: accelerated failure time model; heteroscedasticity; information criteria; interval censoring; proportional hazards model; proportional odds model; seminonparametric (SNP) density; time-dependent covariates
MeSH headings : Biometry / methods; Computer Simulation; Data Interpretation, Statistical; Models, Statistical; Regression Analysis; Statistics, Nonparametric
TL;DR:
A general framework for regression analysis of time-to-event data subject to arbitrary patterns of censoring is proposed, which allows popular models, such as the proportional hazards, proportional odds, and accelerated failure time models, to be placed in a common framework and provides a principled basis for choosing among them.

2007 article
Covariate adjustment for two-sample treatment comparisons in randomized clinical trials: A principled yet flexible approach
Tsiatis, A. A., Davidian, M., Zhang, M., & Lu, X. (2008, October 15). STATISTICS IN MEDICINE, Vol. 27, pp. 4658–4677.
author keywords: baseline variables; clinical trials; covariate adjustment; efficiency; semiparametric theory; variable selection
MeSH headings : Algorithms; Data Interpretation, Statistical; Humans; Randomized Controlled Trials as Topic / statistics & numerical data; Sampling Studies; Statistics, Nonparametric; Treatment Outcome
TL;DR:
App appealing to the theory of semiparametrics is led naturally to a characterization of all treatment effect estimators and to principled, practically feasible methods for covariate adjustment that yield the desired gains in efficiency and that allow covariate relationships to be identified and exploited while circumventing the usual concerns.
