Nonlinear associations of triglyceride-glucose index and body mass index with stroke. A, C Distribution for TyG and BMI; B, D Graphs show HRs for stroke adjusted for age, gender, marital status, residence, education level, smoking status, and drinking status, hypertension, diabetes, heart disease, dyslipidaemia, kidney disease, and history of medication use for hypertension, diabetes, and dyslipidaemia. Data were fitted by Cox proportional hazards regression models. Solid lines indicate HRs, and shadow shapes indicate 95% CIs. Abbreviations: BMI, body mass index; CI, confidence interval; TyG, triglyceride-glucose
