ProtFI, an efficient frailty-trained proteomics-based biomarker of aging, robustly predicts age-related decline
Swier Garst,[...], P Eline Slagboom, Joyce van Meurs | 18-05-2026 | Because individuals age at different rates, robust aging biomarkers are needed beyond chronological age. However, the methodological choices that shape such biomarkers have not been compared in a unified framework. This study addresses that gap by evaluating model choice, training targets, and protein [...]
