Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Quote: "They were than randomly assigned to the behavior therapy (n=9) and control group (n=9) by lottery method." |
Allocation concealment (selection bias) | Unclear risk | Nothing information provided. |
Blinding of participants and personnel (performance bias) All outcomes | Unclear risk | The control was commented on. It was unclear with the intervention group, and the personnel. |
Blinding of outcome assessment (detection bias) All outcomes | Unclear risk | No information provided. |
Incomplete outcome data (attrition bias) All outcomes | Unclear risk | All data were reported, including dropout rates. The distribution of dropout was similar across groups (1 vs 3), but the reasons for dropout were not specified, neither was the time point for dropout. |
Selective reporting (reporting bias) | Unclear risk | No protocol provided. |
Other bias | Low risk | No other apparent sources of bias. |
