aA value of 1 reflects the average Pace of Aging in the Dunedin Study birth cohort over the age 26–45 follow-up period. A value of 1.01 therefore reflects a pace of aging 1% faster than the Dunedin Study norm
bPhenoAge represents the age in years at which average mortality risk in NHANES III matches the mortality risk predicted by the PhenoAge algorithm
cGrimAge represents the age in years at which average mortality risk in the Framingham Heart Study Offspring cohort matches predicted mortality risk
