Risk of bias assessment: randomised controlled trial
Was the trial double-blinded?
- Trial was double-blinded but may have limitations (eg method of blinding inappropriate, tablet vs injection with no double-dummy, different treatment schedules, side-effects may unblind)
single-blinded (eg outcomes assessed blind, objective outcomes, no revealing side-effects).
Was the treatment allocation schedule concealed?
- Adequately concealed (e.g. central randomisation, numbered or coded bottles, drugs prepared by pharmacy).
Were all randomised participants included in the analysis?
- No exclusions or survival analysis used with all subjects included (>95% follow-up for all groups).
