Fig. 2

Smooth curve fitting for (a) Lipid Accumulation Products Index (LAP), (b) Triglyceride Glucose Index (TyG), (c) Waist Triglyceride Index (WTI), (d) Weight-adjusted-waist Index (WWI), (e) A Body Shape Index (ABSI) and ED. The area between the upper and lower blue dotted lines is on behalf of 95% CI. The red dotted line indicates that the positivelinear association between LAP, TyG, WTI, WWI, ABSI and ED are proven by generalized additive model.
