Restricted cubic spline plots of the associations between TyG (A), TyG-WC (B), TyG-WHtR (C), TyG-WHR (D), TyG-BMI (E) and risk of breast cancer. The associations were adjusted for age, race, Townsend Deprivation Index, walking, education, smoking, drinking, family history of breast cancer, history of cardiovascular diseases, screening, contraceptives, age at menarche, number of live births, hormone replacement therapy, age at menopause, diabetes, fasting time, cholesterol, high-density cholesterol. TyG, triglyceride-glucose; TyG-WC, triglyceride glucose-waist circumference; TyG-WHtR, triglyceride glucose-waist to height ratio; TyG-WHR, triglyceride glucose-waist to hip ratio; TyG-BMI, triglyceride glucose-body mass index; CI, confidence interval
