Comparison of the frequency of HLA-DR alleles carried on HLA-B27 positive haplotype between patients with familial spondyloarthropathy and the French control population*

HLA-DR allelePatients haplotypes (n=81)Control haplotypes (n=184)p/pcorr†OR (95% CI)
OR, odds ratio; CI, confidence interval.
*Except where otherwise indicated, values are the number (%) of haplotypes;†statistical comparisons were performed, using Fisher's exact test. pcorr=p value corrected for the number of comparisons.
