SBP: systolic blood pressure; DBP: diastolic blood pressure

^*One study might provide multiple cohorts and data points (e.g., different baseline age, sex, follow-up, and ethnicity). Thus, the 50 cohort studies provided 90 cohorts with different baseline age groups, and 617 data points for SBP, for example. In total, 49 studies reported SBP and 47 studies reported DBP.

^§Data points: correlation coefficients reported for various study sample groups.

^†Based on SBP data.
