WebJan 8, 2024 · There are a few approaches to performing propensity score analyses, including stratifying by the propensity score, propensity matching, and inverse probability of treatment weighting (IPTW). Described here is the use of IPTW to balance baseline comorbidities in a cohort of patients within the US Military Health System Data Repository (MDR). WebUse predicted values from the models to calculate stabilized weights Estimate the IPW estimate of HAART on mortality: Fit weighted pooled logistic model using the estimated stabilized weights. Use “robust” variance estimators (GEE) to allow for correlated observations created by weighting – conservative 95% CI.
