Prognostic impact from clinic, daytime, and night-time systolic blood pressure in nine cohorts of 13,844 patients with hypertension

To determine which SBP measure best predicts cardiovascular events (CVEs) independently, a systematic review was conducted for cohorts with all patients diagnosed with hypertension, 1+ years follow-up, and coronary artery disease and stroke outcomes. Lead investigators provided ad hoc analyses for each cohort. Meta-analyses gave hazard ratios from clinic SBP (CSBP), daytime SBP (DSBP), and night-time SBP (NSBP). Coefficients of variation of SBP measured dispersion. Nine cohorts (n = 13,844) were from Europe, Brazil, and Japan. For sleep-wake SBP classification, seven cohorts used patient-specific information.
