Relationship between newborn epigenetic gestational age at birth based on cord blood DNA methylation data, chronological gestational age at birth, and gestational age acceleration. Panels A-B) show the scatterplot of chronological gestational age at birth and Bohlin’s gestational age clock in CHILD and START, respectively. Panels C-D) show the scatterplot of chronological gestational age at birth and gestational age acceleration in CHILD and START, respectively. The black lines are the best-fitted line using ordinary least squares, with equations displayed in Panels A) and B). The red lines indicate the reference line of y = x
