Change in steps	Baseline pain	3.05 (− 4.16, 10.25)	0.4061
Change in steps	Change in pain	3.11 (− 6.10, 12.31)	0.5065
Baseline 6MWT	Baseline pain	0.51 (0.20, 0.82)	0.0013
Change in 6MWT	Baseline pain	− 0.08 (− 0.30, 0.14)	0.4617
Change in 6MWT	Change in pain	0.30 (0.03, 0.58)	0.0312

Generalized linear regression models evaluating relationships between bodily pain score, change in bodily pain score, daily step counts, change in daily step counts, 6MWT distance, and change in 6MWT distance. Models adjusted for age, BMI, percent predicted FEV₁, dyspnea, and cohort. When relevant, additional covariates for group, season at time of enrollment, and baseline 6MWT distance or baseline daily step counts were included. Steps indicate average daily step counts and 6MWT indicates 6MWT distance as measured in meters. Unit of change for bodily pain is 1 point
