Table 2.
Proportion of cases and controls with 0, 1, or 2 copies of haplotype DRB1*1501-DQA1*0102-DQB1*0602, and overall haplotype frequencies between cases and controls.
| Number of copies | Cases (% with haplotype) | Controls (% with haplotype) |
|---|---|---|
| 0 | 539 (60.8%) | 754 (62.3%) |
| 1 | 318 (35.9%) | 385 (31.8%) |
| 2 | 30 (3.4%) | 72 (5.9%) |

Refers to haplotype frequencies and percentages in cases and controls, where each individual contributes two haplotypes to the total count
