Adjusted Nelson–Aalen Estimators by Inverse Treatment Probability Weighting With an Estimated Propensity Score

Statistics in Medicine
ABSTRACTInverse probability of treatment weighting (IPW) has been well applied in causal inference to estimate population‐level estimands from observational studies. For time‐to‐event outcomes, the failure time distribution can be estimated by estimating the cumulative hazard in the presence of random right censoring.

Effectiveness of pudendal nerve block in the management of acute post-hemorrhoidectomy pain in Asian individuals using inverse probability of treatment weighting (IPTW)

Asian Journal of Surgery
Background: Inadequate management of acute post-haemorrhoidectomy pain is a major concern. Optimal pain management is necessary to reduce acute postoperative pain and improve care quality. Therefore, we investigated the efficacy of postoperative pudendal

Variance Estimation for the Inverse Probability of Treatment Weighted Kaplan Meier Estimator

In a widely cited paper, Xie and Liu (henceforth XL) proposed to use inverse probability of treatment weighting (IPTW) to account for possible confounding in observational studies with survival endpoints subject to right censoring. Their proposal includes an IPTW Kaplan-Meier (KM) estimator for the survival function of a treatment-specific potential ...
