Imaging-based body fat depots and new-onset atrial fibrillation in general population: a prospective cohort study

Table 3 Associations between various CT-based fat depots and incident atrial fibrillation

CT-based	Hazard ratio (95% confidence interval)
CT-based	Model 1 (N = 2139)	Model 2 (N = 2139)	Model 3^a (N = 1297)	Model 4^b (N = 1297)
Liver fat	1.10 (0.94–1.28)	1.06 (0.90–1.25)	1.08 (0.88–1.32)	1.05 (0.86–1.29)
Epicardial fat	1.31 (1.13–1.51)	1.27 (1.09–1.48)	1.16 (0.95–1.42)	1.09 (0.87–1.38)

Values are shown as hazard ratios and 95% confidence interval per 1 standard deviation increase of corresponding fat depots
Abbreviations CT computed tomography
Model 1 was adjusted for sex and age
Model 2 was additionally adjusted for high-density lipoprotein cholesterol, total cholesterol, smoking, total alcohol intake, lipid-lowering medication and cardiac medication and history of hypertension, left ventricular hypertrophy, diabetes mellitus, heart failure, and coronary heart disease
