SNPs showed significant differences in risk allele frequency and genotype distribution between isolated fasting hyperglycemia and isolated postprandial hyperglycemia.

aRisk alleles for type 2 diabetes in Caucasians are denoted in bold.Allelic frequencies between isolated fasting hyperglycemia and isolated postprandial hyperglycemia were compared using χ2 test.Genotype distributions are shown as the counts of three genotypes (BB, Bb, bb). B, risk allele; b, non-risk allele. Genotype distributions between isolated fasting hyperglycemia and isolated postprandial hyperglycemia were compared using Cochran-Armitage trend test.Comparisons of allele frequency and genotype distribution of the rest SNPs are shown in Table S6.p values IFH, isolated fasting hyperglycemia; IPH, isolated postprandial hyperglycemia.
