The distribution of HLA-DR in the study population (n=166) in comparison with the blood donors (n=2400). This comparison is expressed as odds ratios (ORs) and 95% confidence intervals (95% CI)
| HLA-DR alleles | Study population positive | Blood donors positive | OR (95% CI) |
|---|---|---|---|
| DR1 | 37 | 472 | 1.2 (0.8 to 1.7) |
| DR2 | 37 | 688 | 0.7 (0.5 to 1.1) |
| DR3 | 41 | 598 | 1.0 (0.1 to 1.4) |
| DR4 | 51 | 679 | 1.1 (0.8 to 1.6) |
| DR5 | 35 | 453 | 1.1 (0.8 to 1.7) |
| DR6 | 59 | 806 | 1.1 (0.8 to 1.5) |
| DR7 | 31 | 460 | 1.0 (0.6 to 1.5) |
| DR8 | 7 | 128 | 0.8 (0.3 to 1.8) |
