Table 1 Biases and limits of agreement between blood pressure measurement techniques for each level of blood pressure
From: Arterial blood pressure monitoring in overweight critically ill patients: invasive or noninvasive?
Arterial blood pressure | Mean bias | Upper limit of agreement | Lower limit of agreement |

Auscultatory | -6.7 ± 4.3 | 55.1 | -68.5 |
Oscillometric | -15.2 ± 3.7 | 37.7 | -68.2 |
Diastolic blood pressure (mmHg) | |||
Auscultatory | 11.4 ± 2.3 | 44.8 | -22.1 |
Oscillometric | -3.7 ± 2.0 | 25.5 | -33.0 |
Mean blood pressure (mmHg) | |||
Auscultatory | 7.9 ± 2.7 | 47.6 | -31.6 |
Oscillometric | -4.6 ± 2.5 | 31.1 | -40.3 |
