Pairwise relationships between chronological gestational age (GA), epigenetic gestational age (EGA), and epigenetic age (EA) at birth. EGA was estimated using the Bohlin and Knight clocks, and EA was estimated using the Horvath and skin & blood clocks in cord blood (N = 485). The upper panels show the Pearson’s correlation coefficient (r), p-value (p), and median absolute error (MAE) between each pair of variables. The panels on the diagonal show the distributions of each variable. The lower panels show scatter plots of each pair of variables, with the linear trendline and 95% CI plotted as a solid line and shaded area and the identity line plotted as a dashed line
