GPT and diabetes mellitus: Lower Aβ40 was associated with older age (β=−0.09, 95%CI=−0.17 – −0.01, p=0.030), higher BMI (β=−0.18, 95%CI=−0.26 – −0.10, p<0.001), higher eGFR (β=−0.49, 95%CI=−0.60 – −0.38, p<0.001), and lower rates of diabetes (β=0.29, 95%CI=0.13 – 0.46, p=0.001); no other factors were significant (ALT β=−0.08, 95%CI=−0.16 – 0.00, p=0.050; all other p≥0.14).
