Inverse Probability Weighting with Missing Predictors of Treatment Assignment or Missingness [PDF]
Communications in Statistics - Theory and Methods, 2014 Inverse probability weighting (IPW) can deal with confounding in non randomized studies. The inverse weights are probabilities of treatment assignment (propensity scores), estimated by regressing assignment on predictors. Problems arise if predictors can be missing.

Splenic hilar lymph node dissection enhances survival in Bormann type 4 gastric cancer
Scientific Reports, 2023 Splenic hilar (no.10) lymph node dissection during total gastrectomy is no longer recommended for advanced proximal gastric cancer. However, the treatment efficacy of no.10 lymph node dissection in Borrmann type 4 tumors remains unclear.

Time‐varying effect of sex on prognosis of lung adenocarcinoma surgical patients in China
Thoracic Cancer, 2021 Background Little is known about the prognostic advantage of sex for pulmonary adenocarcinoma among Chinese patients. In this study, we aimed to investigate the true sex differences in prognosis by adjusting for confounders and to explore whether the ...

Joint calibrated estimation of inverse probability of treatment and censoring weights for marginal structural models [PDF]
Biometrics, 2020 AbstractMarginal structural models (MSMs) with inverse probability weighted estimators (IPWEs) are widely used to estimate causal effects of treatment sequences on longitudinal outcomes in the presence of time‐varying confounding and dependent censoring.

Comparison of Disease-Free Survival of Breast-Conserving Surgery and Mastectomy Using Propensity Score as Inverse Probability Treatment Weighting [PDF]
Middle East Journal of Cancer, 2023 Background: Survival after breast conserving surgery (BCS) vs. modified radical mastectomy (MRM) is a controversial issue. In this study, we want to compare the disease-free survival (DFS) of women who underwent BCS with those treated by MRM.Method: In ...

Modeling time‐varying exposure using inverse probability of treatment weights
Biometrical Journal, 2017 AbstractFor estimating the causal effect of treatment exposure on the occurrence of adverse events, inverse probability weights (IPW) can be used in marginal structural models to correct for time‐dependent confounding. The R package ipw allows IPW estimation by modeling the relationship between the exposure and confounders via several regression models,

Adjustment for treatment changes in epilepsy trials: A comparison of causal methods for time-to-event outcomes [PDF]
, 2017 BACKGROUND: When trials are subject to departures from randomised treatment, simple statistical methods that aim to estimate treatment efficacy, such as per protocol or as treated analyses, typically introduce selection bias. More appropriate methods to
