Associations of TyG index and incidence of pre-frail and frail statustransition. (A) Kaplan-Meier curve for TyG index and incidence of pre-frail status transition. (B) Adjusted association between TyG index and incidence of pre-frail status transition. (C) Kaplan-Meier curve for TyG index and incidence of frail status transition. (D) Adjusted associationbetween TyG index and incidence of frail status transition. All the adjusted models includedcovariates of age, sex, BMI, residence, marriage, education, habits of smoking and drinking, physical activity, CVD, hypertension, dyslipidemia, diabetes mellitus, cancer, lung disease, stroke, kidney disease, medications, and SBP.
