  1. The complete dataset allelotyped for human leukocyte antigen (HLA)-B includes 681 BD cases and 414 controls, and the subset of HLA-B*51-negative individuals is composed of 227 BD cases and 323 controls. Other (first column) includes alleles with a frequency ≤2.0% in the control group. Nominally significant P-values are highlighted in bold and the respective odds ratio and 95% CI are indicated.
