Intervention
fatigue
The interventions started from March 2018 to January 2020. The last booster session ended in July 2020. The COMB (i.e., the experimental) group received a 16-week programme with a combination of individualised exercise training and the BCE programme. The EXER group (i.e., the active control) received another 16-week programme with a combination of exercise and health talks. To understand the change in the fatigue levels and other physio-psychosocial parameters of our target population, in this study the control group (i.e., a passive control) received health talks with no other intervention. To control the group and social interaction effects of the BCE programme for the COMB group, the number and timing of the health talks for the other two groups were similar to those in the BCE sessions. That means that one health talk per week was arranged from weeks 1–3, and then one per month in weeks 4, 8, and 12, and one 2 months and 6 months after the completion of the entire programme, respectively. The detailed intervention protocol has been published elsewhere [Overview of the intervention for the COMB group
