From: No evidence for association of MTHFR 677C>T and 1298A>C variants with placental DNA methylation

  N Sex; N male (%) Gestational age (weeks); median (range) Maternal ethnicity; N Caucasian (%) Birth weight (SD); median (range)
Reference (677CC + 1298AA) 10 4 (40) 39.0 (36.1–41.6) 8 (80 %) 0.055 (− 1.13–1.40)
High-risk 677 (677TT + 1298AA) 10 4 (40) 37.9 (34.6–40.3) 6 (60 %) − 0.13 (− 2.97–0.70)
High-risk 1298 (677CC + 1298CC) 10 5 (50) 39.4 (38.6–40.7) 8 (80 %) 0.005 (− 1.61–2.20)
  1. p values were calculated in comparison to the reference group by Fisher’s exact test for categorical variables and Mann-Whitney test for continuous variables
