  1. CI confidence interval
  2. aAdjusted difference for baseline value and stratification categories (age and sex)
  3. bInternational Physical Activity Questionnaire (IPAQ): the amount of metabolic equivalent (MET) minutes = minutes reported per category—× 4 (moderate), × 8 (vigorous) and × 3.3 (walking). Total activity = sum of MET minutes
  4. cBrief Illness Perception Questionnaire (IPQ): scale for all responses ranges from 0 to 10. High scores on timeline, consequences, identity, concern and emotional representation reflect a more threatening/poor general health. High scores on the personal control, treatment control and coherence dimensions represent positive beliefs about the controllability of the illness and a personal understanding of the condition
