Metabolomic aging and mortality clocks based on ensemble learning identify systemic aging risk across the human life span in 18,476 individuals.
Aging is characterized by progressive functional decline, yet metabolomic signatures across the human life span remain incompletely defined. Here, we profiled plasma metabolomes from 18,476 participants aged 1 to 96 years across six centers in China using nano-assisted laser desorption/ionization mass spectrometry (LDI...
