Figure 2

Bland and Altman plot for the agreement between HRVT_DMAX1 and LT₁ (a), and HRVT_DMAX2 and LT₂ (c), with bias (continuous line) and the 95% limits of agreement (discontinuous lines) for speed measures. The relationship between HRVT_DMAX1 for speed and LT₁ (b) and HRVT_DMAX2 and LT₂ (d) measures; solid and dashed lines represent the regression line and the 95% confidence intervals, respectively.
