| Methods |
Randomised trial with concurrent eligible patients outside of the RCT. We do not know why the non‐RCT patients were not in the RCT. Patients who would benefit from view of the gallbladder. No losses to follow up. |
| Data |
Characteristics of non‐RCT patients presented and compared to RCT patients who received the same treatment. Cerultide RCT patients were between 29 and 83 years, 1 woman and 16 men. Ceruletide non‐RCT patients were between 19 and 71 years, 21 women and 43 men. The measuring times were different for the RCT patients and the eligible non‐RCT patients. |
| Comparisons |
Two RCT arms, the experimental treatment was compared with similarly treated eligible non‐RCT patients. Experimental: ceruletide‐assisted cholecystography. Control: fatty meal‐ assisted cholecystography. |
| Outcomes |
Clinical outcomes were assessed in all the patients. Patients in the RCT were followed for 40 min, patients in the non‐RCT group were followed for 30 min. Main outcome was lack of reduction in gallbladder area at 20 min. |
| Notes |
The experimental treatment was more effective than control. |
