Systematic review of all randomised and quasi-randomised controlled trials of
  • Patients: acute stroke
  • Intervention: iv glycerol compared with placebo or control
  • Outcome: death, disability, adverse effects

    Articles found in all languages using Cochrane Stroke Group Trials Register, to December 1999 (search terms: detailed in text ) and searching conference proceedings and contacting some trialists.

    Selection criteria: by 2 independent reviewers
    Appraisal criteria: by 2 independent reviewers based on randomisation, type of allocation concealment, blinding, intention-to-treat analysis, follow-up
