Participants |
Number randomised: 18 180 participants were identified through nurse‐led follow‐up clinics; 29 responded as interested, 11 were screened out due to ineligibility, 9 were randomised to intervention, 9 were randomised to control, 1 was lost to follow‐up Inclusion: histologically confirmed colon cancer, which had been resected 6 to 24 months previously Exclusion: existing participation in regular physical activity; Karnofsky rating < 80; unstable angina; uncontrolled hypertension; recent myocardial infarction or a pacemaker Age, years (SD): 52 to 80 (69) Intervention arm: 67.9 (5.7) Control arm: 70.3 (8.7) Gender: Intervention: 5 male, 4 female Control: 7 male, 2 female Ethnicity: NR Type of cancer: colon Therapy previously received for cancer: surgery: n = 17, chemotherapy: n = 6, palliative care: n = 1 Cancer stage: NR Baseline physical activity: chair sit‐to‐stand reps Intervention arm: 10 median (range 8 to 16) Control arm: 10 median (range 7 to 16) Education: NR |

Interventions |
Comparison: supervised and home‐based exercise with dietary advice vs cancer follow‐up service Intervention: 12‐week lifestyle intervention made up of supervised and home‐based exercise sessions and dietary advice. Exercise sessions took place within a dedicated exercise suite at Sheffield Hallam University and were supervised by an experienced exercise physiologist. During the first 6 weeks, participants attended 2 group‐based supervised exercise sessions per week. During the final 6 weeks, participants attended the university facility once a week and were asked to perform 2 home‐based exercise sessions a week. Participants were also provided with a nutrition advice info pack on a fortnightly basis throughout the intervention and engaged in healthy eating seminars in a group format Control: holistic nurse‐led colorectal cancer follow‐up service |

Outcomes |
Dietary changes: 3‐day diaries kept by the participant to self‐report food intake Changes in weight/anthropometry: weight, height, BMI, and hip‐to‐waist ratio measured by exercise physiologist Quality of life: FACT‐C used to assess disease‐specific QoL Duration of follow‐up: 12 weeks |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Patients were randomised by an independent researcher via code numbers using nQuery statistical software |
Allocation concealment (selection bias) | Low risk | Randomisation was undertaken by a senior academic who was not directly involved in recruitment or assessment of patients. The randomisation sequence was not disclosed to the researcher responsible for day‐to‐day running of the trial until patients had completed baseline assessments |
Blinding of participants and personnel (performance bias) Objective outcomes | Low risk | No blinding; outcome is not likely to be influenced by lack of blinding |
Blinding of participants and personnel (performance bias) Subjective outcomes | High risk | No blinding; outcome is likely to be influenced by lack of blinding |
Blinding of outcome assessment (detection bias) Objective outcomes | Low risk | Assessor of outcomes was blinded to group allocation |
Blinding of outcome assessment (detection bias) Subjective outcomes | High risk | No blinding of outcome assessment; outcome measurement was patient self‐reported and therefore is likely to be influenced by lack of blinding |
Incomplete outcome data (attrition bias) Objective | Low risk | Only 1 person dropped out due to stroke (6% attrition). ITT was used |
Incomplete outcome data (attrition bias) Subjective | Low risk | Only 1 person dropped out due to stroke (6% attrition). ITT was used |
Selective reporting (reporting bias) | Unclear risk | Insufficient information to permit judgement |
Other bias | Unclear risk | Insufficient information |
