Fig 1 Reproducibility of (A) V̇o2, (B) V̇e, and (C) heart rate measured on 2 repeated 6MWTs and during 5 minutes of recovery; mean ± SD. Abbreviations: NS, not significant; 6WT-1, 6-minute walk test measurement 1; 6WT-2, 6-minute walk test measurement 2.

Fig 2 Bland-Altman plot of cardiorespiratory parameters (A) V̇o2peak, (B) V̇epeak, (C) peak heart rate, and (D) distance walked between measurements 1 and 2. The x axes show means of peak cardiorespiratory parameters and distance walked from both tests; the y axes show the differences between peak cardiorespiratory parameters and distance walked during measurements 1 and 2. Abbreviation: HRpeak, peak heart rate.
