Graphs showing the correlation between the retinal vascular area and age or blood pressure. A, Correlation between the total arteriolar area and age (left); R = –0.32, n = 10 571, and P < 0.001. Correlation between the total venular area and age (right); R = –0.54, n = 10 571, and P < 0.001. B, Correlation between (top row) systolic blood pressure (SBP) and the total arteriolar area (R = –0.29, n = 10 571, and P < 0.001) or the total venular area (R = –0.25, n = 10 571, and P < 0.001) and between (bottom row) diastolic blood pressure (DBP) and the total arteriolar area (R = –0.26, n = 10 571, and P < 0.001) or the total venular area (R = –0.22, n = 10 571, and P < 0.001).
