WebSep 30, 2024 · After rigorous adjusting for baseline confounders by re-weighting the data with the IPTW the favorable association between second-line and longer OS weakened but prevailed. The median OS was 6.1 months in the second-line + ASC group and 3.2 months in the ASC group, respectively (IPTW-adjusted HR = 0.40, 95% CI: 0.24–0.69, p = 0.001). WebAccording to Lee and Little 2024, when using propensity score (PS) methods, weighting on odds will generate the Average Treatment Effect on the Treated (ATT), while using subclassification and weighting by the inverse probability of treatment (IPTW) will result in the effect being measured on the Average Treatment Effect on the entire sample (ATE).

WebApr 14, 2024 · When the outcome model is incorrectly specified but the treatment model is correctly specified, IPW will generally do better than regression in terms of bias. There is severe imbalance. IPW does not perform well in cases of severe imbalance because the weights will be extreme. This doesn't affect regression much. on my cream
