  1. Frequencies are shown in parentheses in the Controls and Cases columns
  2. (A) Bw4: HLA-B alleles encoding either Threonine at codon 80 (80T) or Isoleucine at codon 80 (80I)
  3. Bw6: HLA-B alleles encoding Asparagine at codon 80 (80N)
  4. (C) NS not significant
  5. The p-value of locus-level heterogeneity is 8.75E−02 in the DRB1*15:01-negative stratum, and 3.64E−01 in the DRB1*15:01-positive stratum. For each stratum, the threshold of significance was calculated as 0.05/3 (1.67E−02). Significant p-values are indicated with asterisks
  6. a For each stratum, the evaluation of significance was informed by the significance of overall heterogeneity between cases and controls in that stratum
