Fig. 3From: Association between Chinese visceral adiposity index and risk of stroke incidence in middle-aged and elderly Chinese population: evidence from a large national cohort studyRestricted cubic spline curves for stroke by CVAI after covariate adjustment. Heavy central line represents the estimated adjusted hazard ratio, with shaded ribbons denoting 95% confidence interval. The vertical dotted line indicates the threshold value of CVAI at 99.8. The horizontal dotted line represents the hazard ratio of 1.0. The model is adjusted for sex, SBP, DBP, rural residence, smoking, and alcohol consumption status, region, marital status, education, heart rate, FBG, serum creatinine, TC, LDL, dyslipidemia, hypertension, heart disease, kidney disease, and DMBack to article page
