| Variable | Cuff-tonometry (calibration using bSBP and bDBP) | Cuff-tonometry (calibration using MAP and bDBP) | ||||||
| Mean ± SD | Meandiff ± SDdiff | Limits of agreement | ICC | Mean ± SD | Meandiff ± SDdiff | Limits of agreement | ICC | |
| MAP (mmHg) | 104 ± 11 | 1 ± 4 | −7, 8 | 0.94 | 107 ± 11 | −2 ± 3 | −7, 3 | 0.95 |
| cDBP (mmHg) | 85 ± 10 | 0 ± 2 | −4, 5 | 0.98 | 85 ± 10 | 0 ± 2 | −3, 4 | 0.99 |
| cSBP (mmHg) | 132 ± 16 | 3 ± 6 | −8, 14 | 0.91 | 141 ± 17 | −5 ± 8 | −20, 10 | 0.85 |
| Central PP (mmHg) | 48 ± 13 | 2 ± 5 | −8, 11 | 0.88 | 56 ± 16 | −5 ± 9 | −22, 11 | 0.77 |
All data are presented as mean ± SD, mean difference ± SD of difference (Meandiff ± SDdiff) and limits of agreement and intraclass correlation coefficients (ICC). cDBP, central diastolic pressure; cSBP, central systolic pressure; MAP, mean arterial pressure; PP, pulse pressure.
