2. Fig 1
Comparison of arterial pressure (AP) measurements using a femoral arterial catheter and the TL-200pro device. Bland–Altman plot for MAP (a), SAP (b), and DAP (c) assessed using the TL-200pro device and the femoral arterial catheter. The plots show the bias (black continuous horizontal line) and 95% limits of agreement (bias ±1.96 * sd; black dashed horizontal lines in bold) between TL-200pro-derived AP values and invasively assessed values. The non-uniform relation between differences and mean values of AP variables calculated using mixed models is illustrated by the grey continuous line (with dashed grey lines indicating the corresponding 95% confidence interval).

Four-quadrant plots. Four-quadrant plots with an exclusion zone of 3 mm Hg are shown for MAP (concordance 0.881) (a), SAP (concordance 0.745) (b), and DAP (concordance 0.834) (c).
