Distribution of FY genotypes with the presence and absence of the -67T>C and 265T>C polymorphisms versus the -353T>AIL8 SNP in patients with chronic periodontitis and controls.

aFY genotypes without -67T>C and/or 265T>C SNPs;bFY genotypes with -67T>C and/or 265T>C SNPs in homozygosis or heterozygosis (without DARC expression or lower DARC expression);cp-value = 0.03; OR = 0.25; 95% CI = 0.078- 0.79;
