Which tool is commonly used to assess the methodological quality of randomized trials in reviews?

• A. CONSORT
• B. PRISMA
• C. GRADE
• D. PEDro

Answer: (D)

Focusing on how well a trial was designed and conducted, this item comes down to using a standardized checklist that assesses internal validity and the quality of statistical reporting in randomized trials. The PEDro scale is the tool most commonly used for this purpose in reviews. It targets features like proper random allocation, concealed allocation, similarity of groups at baseline, blinding of participants, therapists, and assessors, adequate follow-up, intention-to-treat analysis, between-group comparisons, and clear reporting of point estimates and variability. This combination helps reviewers judge how trustworthy the trial results are and how likely bias could have affected the findings. Other options serve different purposes: CONSORT focuses on how trials are reported rather than on their methodological quality; PRISMA guides how systematic reviews and meta-analyses themselves are reported; GRADE evaluates the overall certainty or quality of evidence across multiple studies rather than the methodological quality of individual trials.
