Fig. 3From: Traffic-related air pollution and supplemental folic acid intake in relation to DNA methylation in granulosa cellsEffect modification of the association between high versus low NO2 exposure and methylation of cg07287107 (EIF2AK4) by supplemental folic acid intake. Models were adjusted for age and three surrogate variables. The p-value for interaction between NO2 and supplemental folic acid on DNAm at cg07287107 was 0.037Back to article page
