Optimal caliper widths for propensity‐score matching when estimating differences in means and differences in proportions in observational studies

Optimal caliper widths for propensity‐score matching when estimating differences in means and differences in proportions in observational studies

In a study comparing the effects of two treatments, the propensity score is the probability of assignment to one treatment conditional on a subject's measured baseline covariates. Propensity-score matching is increasingly being used to estimate the effects of exposures using observational data. In the most common implementation of propensity-score matching, …
