2. Fig 1
A, Manhattan plot representing results of the meta-analysis, including the Italian and Dutch cohorts. Red and blue lines indicate established (P = 8.04 × 10−7) and suggestive (P = 1.61 × 10−5) significance levels, respectively. B, Manhattan plot showing results obtained in a meta-analysis of the HLA region (unconditioned test). C, Results after conditioning on the HLA-DRB1*0301 classical allele. The red/green color gradient represents the effect direction of each analyzed variant (red for risk and green for protection). Size of diamonds indicates the degree of linkage disequilibrium with the classical allele HLA-DRB1*0301. The red line represents the established significance threshold (P = 8.04 × 10−7).
