2. Figure 1
The relationship between the difference in measured and predicted oxygen consumption (VO2) against predicted VO2. No difference would be represented as a horizontal scattering around 0 (Pearson correlation coefficient = 0.96, P < .001).

3. Figure 2
There was no correlation between body surface area and measured oxygen consumption (Pearson correlation coefficient = −0.02, P = .211).
