Cumulative incidence curves of outcomes for patients according to initiated treatment before and after propensity score weighting method.

The NOAC and warfarin groups both showed a lower cumulative risk of efficacy outcomes compared with the no-treatment group (A). Warfarin group has the highest cumulative risk of safety outcome, while the no-treatment had the lowest cumulative risk of safety event (B). The weighted cumulative risk of composite outcome showed a clear separation of event curves within the three groups, in which the NOAC group had the lowest risk of composite outcome, while the no-treatment group had the highest risk of composite outcome (C).
