* Multivariate logistic regression analyses were performed with forward conditional variable selection method, adjusted by age, gender, body mass index, and transfusion. Cells with dashes indicate that the variable was included in the multivariate model but excluded after the multivariate analysis; †comparator groups for glycemic markers in all multivariate analyses are the opposite group defined by the cutoff value. For example, the comparator group for HbA1c level ≥ 8 is HbA1c level < 8; p values are significant; OR = odds ratio; CI = confidence interval; HbA1c = glycated hemoglobin; FBG = fasting blood glucose.
