Bland-Altman plot of $\stackrel{.}{\text{V}}{\text{O}}_{\mathrm{2}\hspace{0.17em}\text{peak}}$ measured during the cycle test and $\stackrel{.}{\text{V}}{\text{O}}_{\mathrm{2}\max }$ predicted by the Siconolfi step test (visit 2). The mean bias is represented by the solid line and the 95% limits of agreement are represented by the dashed lines.
