In the multiple logistic analysis, we used the infection source as one of the covariants, and by doing so, we could technically exclude the potential confounding effect that might be caused by viral factor(s).
To test whether α-HB levels segregated with glucose dysregulation in general, we grouped together IFG and IGT into one IGT category, and by multiple logistic analysis α-HB was significantly associated with IGT independently of center, sex, age, and BMI, with an odds ratio of 2.51 (C.I.: 1.81 3.49, p<0.0001) for each SD of plasma α HB.
