Restricted cubic spline model for the association between the TyG index and fragility fractures among all the study participants. RCS regression was adjusted for age, sex, educational level, BMI, alcohol consumption, SBP, DBP, HbA1c, albumin, alkaline phosphatase, 25(OH)D, diabetes, hypertension, hyperlipidemia, coronary artery disease, chronic kidney disease, and medication treatments, including insulin drugs, oral hypoglycemic agents, antihypertensive drugs, and lipid-lowering drugs. TyG, triglyceride-glucose; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; HbA1c, glycated hemoglobin; 25(OH)D, 25-hydroxyvitamin D
