Using Propensity Scores for Causal Inference: Pitfalls and Tips

Journal of Epidemiology, 2021
Methods based on propensity score (PS) have become increasingly popular as a tool for causal inference. A better understanding of the relative advantages and disadvantages of the alternative analytic approaches can contribute to the optimal choice and ...

Using inverse probability weighting to address post-outcome collider bias

, 2021
We consider the problem of bias arising from conditioning on a post-outcome collider. We illustrate this with reference to Elwert and Winship (2014) but we go beyond their study to investigate the extent to which inverse probability weighting might offer

Variance estimation in inverse probability weighted Cox models

Biometrics, 2020
AbstractInverse probability weighted Cox models can be used to estimate marginal hazard ratios under different point treatments in observational studies. To obtain variance estimates, the robust sandwich variance estimator is often recommended to account for the induced correlation among weighted observations.

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.

Inverse probability weighting for covariate adjustment in randomized studies [PDF]

Statistics in Medicine, 2013
Covariate adjustment in randomized clinical trials has the potential benefit of precision gain. It also has the potential pitfall of reduced objectivity as it opens the possibility of selecting a ‘favorable’ model that yields strong treatment benefit estimate.
