Restricted cubic spline of the relationship of T2DM with TyG (A), LAP (B), and VAI (C). Potential nonlinear relationships were examined using restricted cubic splines (knots on the 5th, 25th, 75th and 95th percentiles), with hazard ratios (HRs) based on logistic regression models. The dash line represents the OR equal to 1. The ORs was adjusted for age, sex, education, marital status, retirement status, smoking, alcohol drinking, leisure-time physical activity, BMI, SBP, DBP and history of cardiovascular diseases
