    <p><b>A</b> Plot of the <i>HLA</i> region from the meta-analysis (random effects model) of the association between GWAS markers and JCV serostatus in the Scandinavian (n = 634) and German (n = 718) MS cases and the Swedish controls (n = 465) on chromosome 6. The horizontal line represent a p-values of and 1×10<sup>−8</sup>. All analyses were adjusted for gender, age at sampling, and principal components. The most significant SNP is rs34454237 (p<4×10<sup>−14</sup>) which maps 42.6 kb from the <i>HLA-DRB1</i> gene towards the HLA class I genes. <b>B</b> Plot of the <i>HLA</i> region from the meta-analysis (random effects model) of the association between GWAS markers and transformed anti-JCV nOD levels in the anti-JCV antibody positive Scandinavian (n = 374) and German (n = 294) MS cases and the Swedish controls (n = 406). The horizontal lines represent a p-value of and 1×10<sup>−8</sup>. All analyses adjusted for gender, age at sampling, and principal components. The locations of the <i>HLA-A</i>, <i>-C</i>, <i>-B</i>, <i>-DRB1</i>, <i>-DQA1</i> and -<i>DRB1</i> loci are noted using genome build 36. The most significant SNP is rs3129860 (p<1×10<sup>−7</sup>) which maps 145.7 kb from the <i>HLA-DRB1</i> gene in the direction of the <i>HLA</i> class I genes.</p

    <p>Results from the linear regression analysis of the association between HLA-alleles and JCV nOD levels.

P-values that reach nominal significance, 0.05 are marked in bold. The median nOD levels are given among individuals positive or negative for respective <i>HLA</i> allele.

    <p>Studies based on population isolates with a high degree of cryptic relatedness are presented separately. Effect estimates of meta-analyses are shown with green diamonds. I<sup>2</sup> is a measure of the heterogeneity between studies. Random effect meta-analyses are included if I<sup>2</sup>>0.5. Study weights (blue squares) correspond to fixed effect meta-analyses.</p
