Stepwise conditional analysis on HLA-DQα1:160D in validation cohort, using gender as covariate
| CHR | Marker | Case | Control | Non-reference amino-acid | OR (95% CI) | P value |
| 6 | DRB1:96:H | 0.52 | 0.64 | DRB1:96:H | 0.58 (0.49 to 0.68) | 2.80E-10 |
| 6 | DRB1:74:A | 0.61 | 0.56 | DRB1:74:A | 1.59 (1.35 to 1.88) | 5.26E-07 |
P value less than 5.0×10−8 was considered as cut-off.
