- Data are presented as means ± SD or%; group comparisons (impaired vs. unimpaired) were made using the odds ratio test for non-normally distributed continuous variables and the chi-square test for categorical variables; BMI = body mass index, Hb A1C = c-fraction of glycosylated hemoglobin. P values are expressed if they are <0.05.
