| Summary of Findings | From 200 included abstracts, an average reported 60% of PRISMA-A checklist items (mean 8.9 ± 1.7, range 4 to 12). Only 49% described effects in terms meaningful to patients and clinicians (e.g., absolute measures), and only 43% mentioned strengths/limitations of the evidence base. For “negative” outcomes, the authors identified problematic simple restatements (20%), vague “no evidence of effect” wording (9%), and wishful wording statements (8%) which frame non-significant results to reflect the authors’ bias regarding an expected direction. |
