Prediction of gestational age in the PREDO non-ART dataset (n = 148). Panel a shows the scatter plot of predicted gestational age against gestational age estimated by ultrasound using the EPIC GA clock. The corresponding predictions using the Bohlin clock and the Knight clock are shown in panel b and c, respectively. The red line indicates a perfect correlation between DNAm-based gestational age and ultrasound-based gestational age. The black line indicates the MM-type robust regression of ultrasound-based gestational age on DNAm-based gestational age
