EpiAge: a next-generation sequencing-based ELOVL2 epigenetic clock for biological age assessment in saliva and blood across health and disease
Computational/Algorithm Study
2025 Jan 22The study tested the exact same three-CpG epigenetic clock (EpiAgePublic) on over 4,600 people and found it works well for estimating age, matching what the claim says about achieving high accuracy with just three markers.
