WebPropensity score methods that we evaluated were propensity score matching (PSM) using two different algorithms, the inverse probability of treatment weighting (IPTW), covariate adjustment using the propensity score, and propensity score stratification. We defined balance, using standardized differences, as differences of <10% between cohorts. WebDec 13, 2024 · Did you do the most basic versions of propensity score matching and IPTW, or did you do advanced versions that target balance like overlap weighting, cardinality matching, genetic matching, and entropy balancing?
