PCS 12, the physical summary component score. MCS 12, the mental summary component score. Pre-diabetes, IFG (impaired fasting glucose) and/or ITG (impaired glucose tolerance). Results expressed as mean ± SD; M/W, (men/women); NS (nonsignificant).
SS: ANOVA evaluates intragroup differences for age, BMI, educational level, and glucose metabolism status.
∗ P < 0.001, # P < 0.001 denote differences between normal and all of the groups (prediabetes, UKDM, and KDM).
∗∗ P < 0.02 denote pre-diabetes versus known diabetes.
## P < 0.001 denote pre-diabetes versus known diabetes.
+ P < 0.03 denote normal versus pre-diabetes.
