HF incidence by PPCV category. A is totality, B is INTENSIVE = Intensive treatment, C is INTENSIVE = Standard treatment. Incidence of heart failure by pulse pressure variability groups: pulse pressure variability groups were based on pulse pressure coefficient of variation as Low (PPCV ≤ 15.0%), Middle (15.0% < PPCV < 20.0%), and High (PPCV ≥ 20.0%). P < 0.0001 for differences among curves using the log-rank test
