Exposure prediction approaches used in air pollution epidemiology studies: Key findings and future recommendations
JOURNAL OF EXPOSURE SCIENCE AND ENVIRONMENTAL EPIDEMIOLOGY, 23(6), 654–659.
author keywords: exposure metrics; exposure models; air exchange rate; epidemiology; PM2.5; ambient pollution
MeSH headings : Air Pollution; Environmental Exposure; Environmental Monitoring; Epidemiologic Studies; Humans; Particulate Matter

Efficient estimation of the distribution of time to composite endpoint when some endpoints are only partially observed
LIFETIME DATA ANALYSIS, 19(4), 513–546.
author keywords: Augmented inverse probability weighted estimator; Composite endpoint; Missing data; Nelson-Aalen estimator; Semi-parametric efficiency; Withdrawal
MeSH headings : Biostatistics; Clinical Trials as Topic / statistics & numerical data; Computer Simulation; Endpoint Determination / statistics & numerical data; Humans; Linear Models; Longitudinal Studies; Models, Statistical; Proportional Hazards Models; Registries / statistics & numerical data; Statistics, Nonparametric; Time Factors
TL;DR:
The theory of augmented inverse probability weighted estimating equations is used to show how partial information on the composite endpoint for subjects who withdraw from the study can be incorporated in a principled way into the estimation of the distribution of time to composite endpoint, typically leading to increased efficiency without relying on additional assumptions above those that would be made by standard approaches.
