Distribution of <i>FY</i> genotypes with the presence and absence of the <i>-67T>C</i> and 265<i>T</i>><i>C</i> polymorphisms versus the <i>-353T>A</i><i>IL8</i> 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;
