The hallmarks are organized into three tiers: primary causes that initiate damage, antagonistic responses that become harmful when chronic, and integrative consequences that emerge from the accumulated dysfunction.
Intervention Evidence Matrix
Which interventions target which hallmarks?
Evidence grades: A = strong human RCTs, B = good human data, C = promising preclinical/observational, D = early/limited. Dot size is not meaningful — presence indicates the intervention has evidence of targeting that hallmark.
