Values are mean (SD) or number [%] unless stated.
*SF-36 scores are calculated from norm-based scores for a UK population with a mean of 50 and SD 10. A higher score represents better health-related quality of life (self-reported).
†Rivermead mobility index range is 0–15 with a higher score indicating better physical function (self-reported and performance based).
‡Incremental shuttle walk test range is 0–1020 m with a higher distance indicating better exercise capacity (performance based).
§Functional limitations profile range is 0–100 with a lower score indicating better health-related quality of life (self-reported).
¶Visual analogue scale range is 1–100 with a higher score indicating better health-related quality of life (self-reported).
**Index score is derived from value sets for a UK population with a lower score indicating better health-related quality of life (self-reported).
††Percentage predicted score is calculated from norm-based UK values based on age and gender20 (performance based).
‡‡Percentage predicated score is calculated from norm-based UK values based on age and gender21 (performance based).
§§Hospital anxiety and depression scale range is 0–21 with a higher score indicating a higher risk of anxiety/depression (self-reported).
¶¶Range is 1–5 with higher scores indicating greater disability due to breathlessness (self-reported).
***Range is 1–10 with a higher score indicating better self-efficacy to exercise (self-reported).
†††Each stage corresponds to the participants’ motivational readiness to exercise (self-reported).
