Six-Minute Walk Distance in Chronic Obstructive Pulmonary Disease: Reproducibility and Effect of Walking Course Layout and Length
Abstract
The 6-minute walk test is used in clinical practice and clinical trials of lung diseases; however, it is not clear whether replicate tests need to be performed to assess performance. Furthermore, little is known about the impact of walking course layout on test performance. We conducted 6-minute walks on 761 patients with severe emphysema (mean +/- SD FEV1% predicted = 26.3 +/- 7.2) who were participants in the National Emphysema Treatment Trial. Four hundred seventy participants had repeated walks on a separate day. The second test was improved by an average of 7.0 +/- 15.2% (66.1 +/- 146 feet, p < 0.0001, by paired t test), with an intraclass correlation coefficient of 0.88 between days. The course layout had an effect on the distance walked. Participants tested on continuous (circular or oval) courses had a 92.2-foot longer walking distance than those tested on straight (out and back) courses. Course length had no significant effect on walking distance. The training effect found in these patients with severe emphysema is less than in previous reports of patients with chronic obstructive pulmonary disease. Furthermore, the layout of the track may influence the 6-minute walk performance.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
