Patient flow through the study. Note that subjects in the pale grey cell and second dark grey cell reentered the study for the 6-month review. Data were not collected for subjects in dark grey cells.

3. Figure 2
Average 6MWDs for 6MWT1 (black) and 6MWT2 (grey) at CR start, postcompletion, and 6 months postcompletion of a 6-week CR program for the entire sample. The mean predicted value at CR start for healthy adults with the same height, weight, and sex is shown with a dashed line (–– –) at 529m. A significant difference was noted between mean values for 6MWD1 and 6MWD2 at each assessment point (P<.001 using Holm-Sidak pairwise multiple comparison method after 2-factor repeated-measures analysis of variance) to assess mean values.

4. Figure 3
Comparison of 6MWDs for 6MWT1 and 6MWT2 for subjects with complete 6MWD data for all times (n=33): (A) scatterplot and (B) Bland-Altman plot. 6MWD is represented by closed circle at CR start, open circle postcompletion, and closed triangle at 6 months postcompletion of the CR program. (A) Unbroken line (−) represents the linear regression line; the equation is 6MWD2=(1.08×6MWD1)−27.47, with the intercept on the y axis at 352.7m. ICC=0.93 (95% CI, .90–.95). (B) Dotted line (…) represents bias (15.8±28m) and broken lines (- -) represent 95% limits of agreement (−39.9 to 70.6m). Pearson correlation coefficient, r=.37.
