Cohen's kappa = 1.0 indicates perfect inter-rater reliability. The only dimension receiving a score above 1 was 'scientific_premise' (score=3), reflecting the text's adequate grounding in prior literature with proper citations (pmid:28148298, pmid:37118504). All remaining dimensions received score=1 because the source text is a hypothesis/literature synthesis rather than a completed study report—hence missing study design, blinding, power analysis, resource identification, statistical reporting, data availability, and SABV considerations.
