Figure 2. Associations of amino acid residues in DRβ (A), DQβ (B), and DPβ chains (C) with the presence of anti-La/SS-B antibodies.

Figure 2

Corrected P (Pc) values were calculated by multiplying the P value by the number of amino acid residues tested. Associations were established by Fisher’s exact test using 2×2 contingency tables.
