The IPTW-adjusted cumulative incidence of composite cardiovascular outcomes in the FDC of amlodipine 5 mg/atorvastatin 10 mg (green line), FDC of amlodipine 5 mg/atorvastatin 20 mg (blue line), and free combination of amlodipine 5 mg/atorvastatin 10 mg (red line) groups. The cumulative incidence was derived from Kaplan-Meier estimate. CI, confidence interval; FDC, fixed-dose combination; HR, hazard ratio; IPTW, inverse probability of treatment weighting.
