Distribution of the smallest worthwhile effects (SWEs) of water-based pulmonary rehabilitation on 6-min walk distance (in metres) nominated by people with chronic obstructive pulmonary (n=98). Two outlying values (564 and 744 m) are not shown.
- FIGURE 3
Distribution of the differences in smallest worthwhile effects (SWEs) of land-based and water-based pulmonary rehabilitation on 6-min walk distance (in metres) nominated by people with chronic obstructive pulmonary disease. Difference values are water-based SWE minus land-based SWE, so a value to the right of zero indicates that the participant required a greater improvement from pulmonary rehabilitation when the exercise component was water-based to feel that the benefit would outweigh the cost, risk and inconvenience (n=98). Two outlying values (525 and 584 m) are not shown.
