PCSK9 and type 2 diabetes mellitus: Serum PCSK9 levels positively correlated with T2DM (OR = 1.018[1.011–1.025], p < 0.001) when age, sex, BMI, HC, WC, WHR and heart rate were forced in the model and this relationship even existed when lipid levels were forced in the model (OR = 1.017[1.010–1.025], p < 0.001) (Table 3).
