| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Quote: "During the baseline measurements, every participant was given a consecutive number. By using a cut‐off point in the measurements of post‐traumatic stress symptoms, the group was divided into a case (N=137) and a non‐case group (N=69). Depending on whether their number was an even or odd one, participants belonging to the case group were respectively assigned to an intervention group (N=66) or a control group (N=71)" |
