Head pain scores for female MA patients by OPRM1 gene, A118G SNP genotype
| Group | Genotypes | |||
|---|---|---|---|---|
| Migraine pain severity score | AA | AG/GG | Odds ratio* | P value* |
| Low score (n %) | 75 (63) | 12 (35.2) | 3.125 | 0.0037 |
| High score (n %) | 44 (37) | 22 (64.7) | ||
| Total | 119 | 34 | ||
Chi-squared (χ2) analysis revealed significant association between genotypic frequencies for the A118G SNP in the OPRM1 gene and high scores for head pain in MA females. Values are total number genotypes. Significance was taken at P ≤ 0.05
* Odds ratio and P value adjusted for age
