Fig. 4From: U-shaped association between the triglyceride–glucose index and atrial fibrillation incidence in a general population without known cardiovascular diseaseMultivariable-adjusted hazard ratios for AF based on restricted cubic spines among overall individuals. Each hazard ratio was computed with a TyG index level of 8.59 as the reference. The model was adjusted for age, sex, race, body mass index, smoking, drinking, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, use of cholesterol-lowering medication, history of diabetes, hypertension, and peripheral artery disease. The Red line represents references for HRs, and the area between the dotted line represents 95% CI. Histograms represent the frequency distribution of the baseline TyG index. AF atrial fibrillation.
