| Variables | aORa (95% CI) | P-value | |
|---|---|---|---|
| Parental Consanguinity | No | 1 | |
| Yes | 2.17 (1.32–3.54) | 0.002 | |
| Consanguinity Degrees | No consanguinity | 1 | |
| 1st Cousins | 4.1 (2.1–8.02) | <0.001 | |
| 2nd / 3rd Cousins | 1.92 (1.08–3.39) | 0.025 | |
| Other / Distant Cousins | 1.51 (0.6–2.97) | 0.24 | |
| Family History of Vitiligo | No | 1 | |
| Yes | 0.63 (0.4–0.99) | 0.05 | |
| Family History Degrees | No Family History | 1 | |
| 1st / 2nd degree relatives | 0.48 (0.26–0.91) | 0.024 | |
| Other degrees / Distant relatives | 0.73 (0.43–1.25) | 0.25 | |
Note: aaOR was calculated by including gender, nationality, parental consanguinity and family history in the final regression model.
