Model 1: Adjusted for age and gender
Model 2 (TyG-BMI): Additionally adjusted for education, smoking, opium use, LVEF category, physical activity, hypertension, prediabetes/diabetes, dyslipidemia, antidiabetic medication, antihyperlipidemic medication, and energy-adjusted dietary insulin load
Model 2* (Dietary Indices): Additionally adjusted for education, smoking, opium use, LVEF category, physical activity, hypertension, prediabetes/diabetes, dyslipidemia, antidiabetic medication, antihyperlipidemic medication, and TyG-BMI index
Model 3**: Further adjusted for total fiber, fruits, vegetables, meat, dairy, total fat (all in grams/day), and total energy intake (Kcal/day)
