Fig. 4

Consensus frequencies of HLA allele types in healthy controls, African JIA patients, and European JIA patients. A Bar plots showing the consensus frequencies of HLA allele types at HLA class I loci. B Bar plots showing the consensus frequencies of HLA allele types at HLA class II loci. The x- and y-axis indicate the names and frequencies of HLA allele types, respectively. The names of HLA types having significantly different distributions between healthy controls, African JIA patients, and European JIA patients were represented in bold (P < 0.05)
