| Methods |
Randomised trial with concurrent eligible patients outside of the RCT. The non‐RCT patients were not in the RCT because they refused randomisation, but agreed to follow up in a registry. Patients with multivessel coronary artery disease. Losses to follow up unknown. |
| Data |
Characteristics of non‐RCT patients presented and compared to RCT patients who received the same treatment. RCT coronary artery bypass graft surgery patients were mean 61 years, 676 men and 238 women. Non‐RCT coronary artery bypass graft surgery patients were mean 63 years, 462 men and 163 women. |
| Comparisons |
Two RCT arms, both arms were compared with similarly treated eligible non‐RCT patients in a registry. The experimental RCT arm patients underwent percutaneous transluminal coronary angioplasty (PTCA). The control RCT patients underwent coronary artery bypass graft surgery (CABG). |
| Outcomes |
Clinical outcomes were assessed in all patients, they were followed up for 7 years. Main outcome in this study was mortality. |
| Notes |
The experimental treatment resulted in significantly higher mortality than the control treatment. |
