MTHFR and myeloid sarcoma: According to the findings of this study (Figure-2), there was no significant relationship between MTHFR 677 C> T polymorphism and MS in the allele model (T vs. C: P= 0.720; OR = 1.078, 95% CI = 0.715 to 1.626), in the homozygous model (TT vs. CC: P= 0.987, OR = 1.004, 95% CI = 0.596 to 1.693), in the heterozygous model (CT vs. CC: P= 0.390, OR = 1.157, 95% CI = 0.829 to 1.615 ), in the dominant model (CT + TT vs. CC: P= 0.931, OR = 1.020, 95% CI = 0.646 to 1.611) and in the recessive model (TT vs. CT + CC: P= 0.265; OR = 0.799, 95% CI = 0.539 to 1.185).
