  1. Chr, Chromosome; SE, standard error
  2. Effect estimates represent the difference in DNA methylation per 1 µg/L increase in cord blood serum ferritin concentrations. The model was adjusted for gestational age at birth, maternal age at intake, educational level, pre-pregnancy body mass index, smoking, child sex, cell-type proportions, and batch
