What A-grade health sources have in common
Every source on this page combines two filters: a Health publication category and a A-grade SourceScore Index. That intersection means these sources share a structural profile — they meet the editorial and citation-quality bar of A-grade (85–94) AND they operate within the health category's specific publication norms.
The within-facet sub-score means above (93 / 84 / 81) tell you how this facet differs from the A-grade average overall. A higher Discipline mean than the A average means health sources in this band cite more rigorously than other A-grade categories; a lower Modern Reference mean usually flags structural access limitations (paywalls, legacy infrastructure) typical of healthpublishing.
