From: Estimation of central systolic blood pressure using an oscillometric blood pressure monitor
Bland–Altman analyses in the Validation Group (n=50). Data combine baseline and after sublingual nitroglycerin administration measurements. (a) agreement between invasive brachial systolic blood pressure (SBP) and measured aortic SBP; (b) agreement between invasive brachial pressure value of the late systolic shoulder (SBP2) and measured aortic SBP; (c) agreement between measured and predicted aortic SBP by the invasive brachial pressure wave prediction model; Dashed lines indicate the boundaries of two s.d. of the differences. Solid line indicates mean of the differences. CI, confidence interval.
