Peripheral blood DNA methylation values (in %) for each CpG site analyzed in the TCF7L2 promoter in type 2 diabetic patients and age- and BMI-matched controls*.

* Values shown are means ±SD.P values were calculated using the Mann-Whitney U test.Q values were calculated as estimates of the multiple-testing-corrected false discovery rate (FDR).Adjusted P-values were calculated by performing a logistic regression analysis adjusting by age, gender, BMI, physical inactivity, smoking status and waist circumference.Adjusted Q-values were calculated as estimates of the multiple-testing-corrected false discovery rate (FDR) on the adjusted P-values.†CpG dinucleotides have been numbered relative to ATG.‡CpG dinucleotide position has been determined according to the ATG position for the TCF7L2 gene (ENSG00000148737).
