Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk |
Quote: "All patients were randomly assigned to either active or placebo medication." pp. 352 Comments: method of sequence generation not reported. |
Allocation concealment (selection bias) | Unclear risk | Comments: method of allocation concealment not reported. |
Blinding of participants and personnel (performance bias) All outcomes | Low risk | Quote: "To maintain the blind, doses were decreased for equal numbers of placebo patients. The active and placebo pills were identical." pp. 353 |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | Comments: blinding of outcome assessment not reported. However, the study authors state that this trial is 'double‐blind' |
Incomplete outcome data (attrition bias) All outcomes | High risk | Comments: Table 1 presents ITT analysis but per protocol analyses reported. The number excluded from analysis varies |
Selective reporting (reporting bias) | Unclear risk | Comments: no trial protocol available to compare with the publication |
Other bias | Low risk | Comments: there was no statistically significant difference between the treatment and control group in baseline demographic characteristics |
