NEOage clocks - epigenetic clocks to estimate post-menstrual and postnatal age in preterm infants

class="figure-viewer-img"

Figure 6. Scatterplots of measured PNA and PNA estimates by (A) Horvath’s skin-blood clock and (B) PedBE in an external saliva data set (GSE72120 [18]). This saliva data set was measured by the 450k array and included full-term (red) and preterm (blue) infants. The reported prediction performances, RMSE and correlation coefficients, between estimated and measured age metrics are based on preterm infants only.
