p‐values were adjusted using the Benjamini–Hochberg step‐up procedure to account for multiple comparison. The false discovery rate level was controlled at 0.05.
DR, doubly robust method; GLM, generalized linear models fitted by generalized estimation equation; IPW, inverse propensity score weighting method; OLS, classic ordinary least squares regression and robust standard error.
Significant results are denoted by † after multiple‐comparison adjustment.
