Intervention effect on physical activity
Patients who received the PA-telecoaching intervention presented clinically important improvements in steps/day compared to patients in the UCG, at each time point after randomization (Fig. 
Comparison of the changes in PA between patients from both the IG and UCG, adjusted for daylight at each visit point. p-values indicate the interaction effect (with V0 as the reference). PA; physical activity; IG, intervention group; UCG, usual care group; n, number; m, months; PR, pulmonary rehabilitation. Data based on multiple imputation
Comparison of changes in PA between IG and UCG groups. V0 was considered the reference at mixed model analysisValues presented as estimates ± standard error obtained from the mixed model analysis adjusted for daylight. PA, physical activity; MVPA, moderate to vigorous PA. UCG, usual care group; IG, intervention group; min; minutes; m, meter; s, seconds. In case of missing data (for steps/day and MVPA) from the Dynaport Activity Monitor, multiple imputation was performed with the data from the Actigraph as outlined in the methodology section. At V1, V2 and V3, interaction effect with V0 as reference value are displayed
