Evaluative performance of triglyceride-glucose-frailty index versus surrogate insulin resistance indices for advanced cardiovascular-kidney-metabolic syndrome, cardiometabolic multimorbidity, and mortality: the role of estimated glomerular filtration rate
TyG-FI, which captures both metabolic dysfunction and physiological frailty, showed stronger associations with advanced CKM syndrome, prevalent CMM, and mortality than most surrogate insulin resistance indices, and may offer a pragmatic tool for early mortality risk stratification in individuals with high cardiometabol...
