Figure 2

Unadjusted cumulative incidence rates for all-cause deaths in the study population. Cumulative incidence curves are shown for all-cause death in patients with PPM group (a) and in those with ICD group (b). The numbers in each figure represent the cumulative incidence rates at each time point. All p values were calculated with the use of the log-rank test. ICD, implantable cardioverter-defibrillator; PPM, permanent pacemaker.
