Genotype and allele frequencies of the MTHFR C677T polymorphism in case and control groups
| Genotype | Case(N = 61) | Control(N = 61) | χ2values | OR | 95%CI | P values |
|---|---|---|---|---|---|---|
| CC | 5(8.2) | 15(24.6) | 1 | |||
| CT | 30(49.2) | 27(44.3) | 4.559 | 3.333 | 1.068~10.400 | 0.033* |
| TT | 26(42.6) | 19(31.1) | 5.963 | 4.105 | 1.271~13.258 | 0.015* |
| C | 40(32.8) | 57(46.7) | 1 | |||
| T | 82(67.2) | 65(53.3) | 4.945 | 1.798 | 1.070~3.021 | 0.026* |
Note: *P value< 0.05 indicates that the genotype and allele distributions of MTHFR C677T polymorphism exhibit a significant difference between case and control groups
