WebAug 26, 2024 · Inverse probability of treatment weighting (IPTW) can be used to adjust for confounding in observational studies. IPTW uses the propensity score to balance baseline patient characteristics in the exposed and unexposed groups by weighting each individual in the analysis by the inverse probability of receiving his/her actual exposure. disco elysium average playtime
