Associations of amino acid residues in the DRβ chain with YORA (A), MORA (B), and EORA (C). Associations were established by Fisher exact test using 2X2 contingency tables. Corrected P (Pc) values were calculated by multiplying the P value by the number of amino acid residues tested. Positive associations are indicated by filled circles and negative associations by open circles. RA = rheumatoid arthritis, YORA = younger age onset RA, MORA = moderate age onset RA, EORA = elder age onset RA.
