  Figure 1. Bland–Altman plot of differences and means for criterion measured VO2max from a maximal incremental treadmill test and the Ramsbottom et al. Beep test algorithm. The 3 dotted lines with blue shading represent mean bias, green shading represents upper 95% threshold, and red shading represents lower 95% threshold. The center line is either the mean difference or [1.96 × SD of Differences]), while the dotted lines above and below the center are the respective 95% confidence intervals. The solid blue line and the gray shading represent the trendline of proportional bias and the proportional standard error of the slope estimates, respectively.

The 3 dotted lines with blue shading represent mean bias, green shading represents upper 95% threshold, and red shading represents lower 95% threshold. The center line is either the mean difference or [1.96 × SD of Differences]), while the dotted lines above and below the center are the respective 95% confidence intervals. The solid blue line and the gray shading represent the trendline of proportional bias and the proportional standard error of the slope estimates, respectively.
