Fig. 1From: Effects of HLA-DRB1 alleles on susceptibility and clinical manifestations in Japanese patients with adult onset Still’s diseaseAssociation between amino acid residues in the DRβ chain and adult onset Still’s disease. Differences in amino acid residue carrier frequencies were analyzed by Fisher’s exact test using 2 × 2 contingency tables. Corrected p (Pc) values were calculated by multiplying the p value by the number of amino acid residues tested. Predisposing association is indicated by filled circles and protective association by open circlesBack to article page
