Chronic Kidney Disease and Mortality in Implantable Cardioverter-Defibrillator Recipients

Figure 2

Cause-specific mortality according to varying levels of renal dysfunction. For the 3 categories of renal dysfunction, cause-specific mortality is depicted. As expected, sudden cardiac death was the major cause of death in ESRD patients on dialysis (50.0% versus 10.1% (GFR < 60 mL/min) versus 10.3% (GFR ≥ 60 mL/min), Chi Square 𝑃=.010). Number at the top of each bar is the mortality rate; number within the bar is the 𝑛 per group. The Unknown category was reserved for those patients whose cause of death could not be determined. Thus, adding the numbers within the bars for three groups will not equal the 𝑛 given in Table 1.
