Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
Low risk |
Quote: "Each participant was randomly assigned (using a dice) to one of three treatment groups: narrative exposure therapy, supportive counselling, or psychoeducation only." |
| Allocation concealment (selection bias) |
Unclear risk |
Comment: There is no mention of any measures taken to conceal allocation. |
| Incomplete outcome data (attrition bias)
All outcomes |
Low risk |
Comment: One participant dropped out from NET and two from supportive counselling. ITT analyses were performed. Reasons for drop‐out were not fully reported. |
| Selective reporting (reporting bias) |
Low risk |
Comment: All specified outcomes were reported. |
| Other bias |
High risk |
Comment: The issue of researcher allegiance cannot be ruled out. Treatment adherence was not monitored. |
| Blinding of participants and personnel (performance bias)
All outcomes |
Unclear risk |
Comment: Participants were aware of their allocation. |
| Blinding of outcome assessment (detection bias)
All outcomes |
Low risk |
