Mean age: Intervention group: 59.5 Control group: 58.8 Percentage men: Intervention group: 76% (n = 22) Control group: 79% (n = 30) All participants: 75% (n = 52) Number of participants recruited: 69 Participant ethnicity: Not reported. Recruited online or offline? Offline, conventional cardiac rehabilitation. |

| Interventions |
Name of the intervention: No name. Intervention aim: Enhance the maintenance of physical activity after cardiac rehabilitation. Intervention features: Participants were reminded through email and SMS text messages to complete intervention tasks and to log in to the programme. Participants also received tailored messages through both the website and SMS text messages. The programme encouraged participants to plan physical activities, and set themselves goals. The programme also contained an activity calendar for participants to log physical activity levels. How was the intervention introduced to the sample? A physiotherapist presents the intervention to all the participants and provides training on how to use the website. Was there any contact between the researcher/healthcare professional and the sample during the intervention? Participants could message a physiotherapist through the website. Duration of the intervention? 1 year. |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | An online random number generator service was used |
| Allocation concealment (selection bias) | Low risk | Concealed using an online service |
| Blinding of participants and personnel (performance bias) All outcomes | Low risk | There were 2 web‐based intervention conditions: 1 received the tailored version of the website, and the control group received a static, non‐tailored version of the programme |
| Blinding of outcome assessment (detection bias) All outcomes | Low risk | Outcome assessors were blinded to group assignment |
| Incomplete outcome data (attrition bias) All outcomes | High risk | Large attrition rate (72%), with no reasons provided for missing data |
| Selective reporting (reporting bias) | Low risk | Prespecified outcomes outlined in the protocol have been reported |
