In the strongest directly mortality-relevant human evidence provided, higher adherence to a Japanese dietary pattern that included coffee was associated with lower all-cause mortality (hazard ratio 0.91, 95% confidence interval 0.83–0.99) and a 10.2-month longer median…","trust_label":"machine_generated_human_reviewed","editorial_verification":{"status":"human_reviewed","trust_label":"machine_generated_human_reviewed","method":"World ID proof-of-human editorial account","scope":["clinical_integrity","reference_quality","scientific_coherence"],"verification_note":"This Evidence Object is machine-generated and human-reviewed.
