  • a Number of non-redundant peptides or proteins (percentage based upon the larger peptide or protein set.

  • b The HLA-DR allele 0101 is indicated in bold as it was the only allele shared by any two patients.

  • c For the comparison of LA1 + RA2 with each of the other five pairs, p ≤ 0.002 by χ2 test.

  • d For the comparison of LA1 + RA2 with four of the other five pairs, p < 0.01 by χ2 test; the comparison of LA1 + RA2 with LA2 + RA2 was not statistically significant.
