Adjusted hazard ratios of incident peripheral artery disease (PAD) by baseline triglyceride-glucose (TyG) index. Each hazard ratio was computed with a TyG index level of 8.6 as the reference. The hazard ratio was adjusted for age, antihypertensive medication, body mass index, diabetes, drinking status, education level, estimated glomerular filtration rate, factor VIII activity, fibrinogen, leisure time and sport index scores, lipid-lowering medication, low-density lipoprotein cholesterol, race, sex, smoking status, systolic blood pressure, von Willebrand factor, and white blood cell count. Red solid line represents the hazard ratio of TyG index across the whole range. Red dotted lines represent the 95% CI. Blue dotted line is the reference line as hazard ratio = 1. Histograms represent the frequency distribution of baseline TyG index
