Figure 5

Bland–Altman plots comparing the PPG-derived SBP and DBP estimates to their cuff-based counterparts. (a,b) 24-h averages. (c,d) Daytime averages. (e,f) Nighttime averages. The solid lines depict the mean differences (biases), whereas the dashed lines depict the 95% limits of agreement. PPG photoplethysmography, SBP systolic blood pressure, DBP diastolic blood pressure.
