摘要

The propensity score is the conditional probability of assignment to a particular treatment given a vector of observed covariates. Previous theeoretical arguments have shown that subclassification on the scalar propensity score will balance all observed covariates. The procedure is illustrated in a large observational study of treatments for coronary artery disease. Five subclasses are constructed that balance 74 covariates. Balanced subclassification is combined with model-based adjustments to provide estimates of treatment effects within subpopulations. Two appendices address theoretical issues: propensity scores from incomplete data, and the effectiveness of subclassification on the propensity score.
