Bland–Altman plot with multiple measurements per patient of mean arterial pressure (MAP) done with the femoral arterial catheter and the high-fidelity upper arm cuff. The plot shows a mean difference of −0.3 mmHg, an upper limit of agreement of 6.4 (CI, 5.6 to 7.3) mmHg, and a lower limit of agreement of 7.0 (CI, −7.9 to 6.2) mmHg. There is a marker for each of the 110 patients in the graphic.
