WebMay 9, 2024 · We further describe 2 propensity score methods for evaluating the association of treatment or therapy with outcomes, propensity score matching and inverse probability of treatment weighting, and compare to covariate-adjusted regression analysis. WebApr 19, 2024 · Inverse probability of treatment weighting (IPTW) should be used for estimating risk differences particularly when the interest is in estimating the ATE [ 7 ]. When estimating treatment effect on time-to-event outcomes, matching and IPTW result in less biased estimates than stratification or covariate adjustment (Fig. 1) [ 8 ].

Webscore matching using R. A potential drawback of propensity scores when used for matching is that a very large number of subjects may be needed, especially in the control group (Guo & Fraser, 2015).
