Subtypes of HLA-DRB1 alleles showing association to OCB positive and/or OCB negative MS in Norwegian MS patients and healthy controls.

Abbreviations: n = total Norwegian samples available with HLA-DRB1* genotypes of 4 digit solution, i.e. MS patients from the screening and replication are pooled, OCB = oligoclonal bands, OR = odds ratio, CI = confidence interval.aThe results are only shown for alleles with frequencies >5%.bAll p values are uncorrected for multiple testing.c (*1501) p values after stratification for HLA-DRB1*15∶01.
