Cumulative incidence of liver cancer about paracetamol users and non-users in the overlap propensity score-weighted populations. The overlap weight adjusted Kaplan–Meier curves were generated based on the propensity score, and propensity score was derived by multivariate logistic regression conditional on aforementioned covariates in Table 2. The log-rank test was used to compare the survival difference between paracetamol users and non-users
