Figure 2. Left, Scatterplot with regression line for stroke volume (SV), measured by the scale and direct Fick method (64 data pairs; r=0.81); Right, Bland‐Altman analysis with mean error (bias) of −1.58 mL, 95% limits of agreement (LOA) of −21.97 to 18.81 mL, and percentage error (PE) of 36.73%.

Preexercise data denoted with a black circle, and postexercise data denoted with a white circle. MeanSV indicates mean SV for combined scale and Fick measurements.
