Figure 1. Associations of elevated FBG with CSF Aβ42, Aβ42/P-tau ratio, and Aβ42/T-tau ratio, and Aβ42/Aβ40 ratio in non-diabetic cognitively normal elders. The scatter plots depict the relations between FBG and (A) CSF Aβ42, (B) Aβ42/P-tau ratio, and (C) Aβ42/T-tau ratio, and (D) Aβ42/Aβ40 ratio. All models were adjusted for age, sex, educational level, and APOE ε4 status. Abbreviations: FBG, fasting blood glucose; CSF, cerebrospinal fluid; Aβ, β-amyloid; T-tau, total-tau; phosphorylated-tau, P-tau; APOE ε4, apolipoprotein E ε4.
