Agreement between VO2 peak and R peak obtained in the SWT and CEPT.

<p>Bland-Altman plot of the difference between the VO₂ peak of the SWT and CEPT plotted against the mean VO₂ peak of the SWT and CEPT (A) and difference R peak of the SWT and CEPT plotted against the mean R peak of the SWT and CEPT (B).
