Associations between blood pressure (BP) and vascular mortality*

Cause of death	Age at risk (years)	HR for relation with SBP†	HR for relation with DBP†
*DPB = diastolic blood pressure; HR = hazard ratio; SBP = systolic blood pressure.
†The HRs reflect an association between 20 mm Hg lower usual SBP (throughout range down to 115 mm Hg) and 10 mm Hg lower usual DBP (≥75 mm Hg) at the start of the decade.
