Comparison of relevant metabolic variables between 2 regional groups

	Marmara-Central Anatolia group (vs. 5-region group)
	Rule	Exception
Serum lipoprotein(a)	Uniformly lower (by 23%), significantly so in discordant pre-diabetes (40% of sample)	Marginally lower in normoglycemia
Serum apoB-containing lipoproteins	Significantly higher	Diabetes
Apolipoprotein A-I	Significantly higher	Normoglycemia (28% of sample)
HOMA index	Significantly higher	Concordant pre-diabetes
Serum creatinine	Significantly higher in discordant pre-diabetes
Waist circumference	Significantly lower in DM with low A1c and discordant pre-diabetes
Systolic blood pressure	Significantly higher in discordant pre-diabetes

Discordant prediabetes signifies predominant group with HbA1c 5.7-6.49% accompanied by normoglycemia; concordant prediabetes defined as HbA1c 5.7-6.49% accompanied by impaired fasting glucose. Apo - apolipoprotein; DM - diabetes mellitus; HbA1c - glycated hemoglobin; HOMA - homeostatic model assessment
