The dose-response relationship between four visceral obesity indices and prediabetes and diabetes. We employed 3-knots RCS to fit the dose-response relationship between four visceral obesity indices and prediabetes and diabetes. We adjusted the model fully for age, gender, family history of diabetes, hypertension, CHD, smoking, alcohol consumption, creatinine, ALT, and AST. The red solid line represents the curve fitting between variables, and the shaded area indicates the 95% CI of the fit. Abbreviation: BRI, body roundness index; CMI, cardiometabolic index; CVAI, Chinese visceral adiposity index; LAP, lipid accumulation product; CHD, coronary heart disease; ALT, alanine aminotransferase; AST, aspartate aminotransferase
