Claim	C005

Claim: As early as 1987, Mulrow documented that none of the 50 reviews she examined met all eight basic scientific reporting criteria.

BLUF: The claim is accurate. Mulrow's 1987 paper in Annals of Internal Medicine examined 50 reviews from four major medical journals against eight criteria adapted from published guidelines. The best-performing review satisfied only six of the eight criteria; none met all eight.

Probability: Almost certain (95-99%) | Confidence: High
