What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Overall accuracy of DNA methylation clocks across populations
Systematic review comparing accuracy of TruAge vs other epigenetic clocks (Horvath, Hannum, PhenoAge) across diverse populations
Test accuracy in diverse populations and age ranges
Large validation cohort (500+) with diverse ages, ethnicities, and health statuses to establish accuracy across populations
Test performance in specific populations
Cross-sectional validation in specific populations (elderly, diseased, specific ethnicities)
Test ability to distinguish diseased from healthy states
Case-control study comparing biological age in diseased vs healthy controls
Individual-level test performance
