From: Sustaining training effects through physical activity coaching (STEP): a randomized controlled trial
Study design. Four study visits: a visit at randomization (i.e. after 3 months of PR; V0), a visit at the end of PR (i.e. after 6 months of PR; V1), a visit after 3 months of follow-up from PR (V2) and a visit after 6 months of follow-up from PR (V3). Data at the start of PR (i.e. 3 months before randomization) were also used for analysis (V-1). Patients were followed up for 9 months after initiation of the PA telecoaching program. PR, pulmonary rehabilitation; V, visit; UCG, usual care group; IG, intervention group
