Greedy caliper propensity score matching can yield variable estimates of the treatment‐outcome association—A simulation study

Purpose Greedy caliper propensity score (PS) matching is dependent on randomness, which can ultimately affect causal estimates. We sought to investigate the variation introduced by this randomness. Methods Based on a literature search to define the simulation parameters, we simulated 36 cohorts of d...
