Bland Altman analyses for hypotension and hypertension. Bland-Altman Plots of all values, where MAP recorded by IAP was ≤50 mmHg (A and C) or > 70 mmHg (B and D). Differences of IAP and Nexfin®/NIBP (y-axis) are plotted against their common mean (x-axis). Bold dotted lines display the limits of agreement, where 95% (bias±1.96 standard deviation of the difference) of all measurements are located. The middle line shows the mean difference (bias). Percentage error and bias are displayed in the diagrams. MAP: Mean arterial Pressure, PE: Percentage error, IAP: Invasive arterial pressure
