FIGURE 1——Flow of participants and distribution of nonresponders through the study.
Note. PACE = physician-based assessment and counseling for exercise; PACE 4M = PACE intervention condition with measurements at baseline, 8 weeks, 6 months, and 1 year; PACE 2M = PACE intervention condition with measurement at 6 months and 1 year; control 4M = control condition with measurements at baseline, 8 weeks, 6 months, and 1 year; control 2M = control condition with measurement at 6 months and 1 year; not available = participant did not return questionnaire at follow-up measurement but was contacted for next measurements; GPs = general practitioners.
FIGURE 2——Median number of minutes spent per week in physical activity of at least moderate intensity: overall (a) and during leisure time (b) and in the PACE (physician-based assessment and counseling for exercise) intervention condition and the control condition at baseline (T0), 8 weeks (T1), 6 months (T2), and 1 year (T3).
