Risk of bias table
Bias | Authors’ judgment | Support for judgment |
Random sequence generation (selection bias) | Unclear risk | “Then the subjects were randomly assigned to either a drug withdrawal group or a non-drug withdrawal group.” |
Allocation concealment (selection bias) | Unclear risk | Not described |
Blinding of participants and personnel (performance bias) | High risk | Placebos were provided,but these were not identical to their sleep medications.
“using a placebo capsule instead of a nightly sleeping pill.” “During the 2 weeks of total withdrawal, the subjects in the drug withdrawal group were provided with transparent sugar-filled gelatin capsules, with the instruction to take one each night before bedtime in lieu of their habitual sleeping pill. Because there were no brittle diabetics in the study, a small gelatin capsule was filled with 1/16 of a teaspoon of sugar. This inert capsule was designed to enable the subjects to preserve the bedtime ritual of pill taking. They were told of the contents of the capsule and that it might or might not affect their sleep.” “These statements were made despite the fact that the subjects were told very precisely that there was only sugar in the small capsules.” |
Blinding of outcome assessment (detection bias) | High risk | As above |
Incomplete outcome data (attrition bias) | Low risk | It appears to be 100% follow-up. |
Selective reporting (reporting bias) | Unclear risk | There was no evidence of a pre-specified protocol, so it is uncertain if the authors followed a pre-specified data-analysis plan. However, the stated objectives are reported. |
Other bias | Low risk |
