The RCS analysis between the hs-CRP/HDL-C ratio and the risk of IR and T2D. A RCS analysis between the hs-CRP/HDL-C ratio and the risk of IR. B RCS analysis between the hs-CRP/HDL-C ratio and the risk of T2D. The area between blue represents a 95% confidence interval. The red solid dashed line indicates a nonlinear relationship between the ratio and IR. IR, Insulin resistance; T2D, Type 2 diabetes; HDL-C, High-Density Lipoprotein Cholesterol; hs-CRP, High-sensitivity C-reactive protein; RCS, restricted cubic spline; OR, odds ratio; CI, confidence interval
