Figure 1 Mortality Rates by Systolic and Diastolic Blood Pressure
All-cause (solid diamonds, solid lines), cardiac (solid squares, dashed lines) and sudden cardiac (solid circles, dotted lines) mortality rates per 100 person-years by (A) systolic blood pressure quartiles and (B) diastolic blood pressure quartiles.

Figure 2 ICD Benefit by SBP
Kaplan-Meier estimates of probability of all-cause mortality by treatment group among patients with (A) systolic blood pressure (SBP) quartiles 1 to 3 and (B) SBP quartile 4. ICD = implantable cardioverter-defibrillator.
