SBP vs. DBP Multivariable model 1† Multivariable model 2‡
SHR (95%CI)* P SHR (95%CI)* P

BP, blood pressure; CI, confidence interval; DBP, diastolic blood pressure; SBP, systolic blood pressure; SHR, subdistribution hazard ratio.

*

Subdistribution hazard ratios express the risk for increments of 10 mm Hg.

†

Systolic and diastolic blood pressure are included in the same model adjusted for age, race, hypercholesterolemia, cigarette smoking, chronic kidney disease and atrial fibrillation.

‡

Systolic and diastolic blood pressure are included in the same model adjusted for age, race, hypercholesterolemia, cigarette smoking, chronic kidney disease, atrial fibrillation and two or more antihypertensive drugs use.
