Application of Propensity Score Methods to Address Missing Data in a Trial on the Effect of Energy Protein Supplementation Among Pulmonary TB-HIV Patients in Mwanza, Tanzania
This study evaluated propensity score inverse probability weighting (PS-IPW) and multiple imputation (MI) against complete case analysis for handling monotonic missing data in a pulmonary TB-HIV supplementation trial in Tanzania, finding that while both advanced methods outperformed traditional analysis in bias and efficiency, none revealed statistically significant treatment effects.
