Fig. 5: Oscillatory characteristics of HUVECs from preterm and term neonates by gestational age.
From: Circadian clock activity in human umbilical vein endothelial cells of preterm and term neonates
Plots show the median and 95% CI of infants with gestational age at birth ≥37 wks (black square, n = 26) vs. 32 + 0–36 + 6 wks (crossed circle, n = 18) vs. 28 + 0–31 + 6 wks (open circle, n = 7) vs. <28 wks (black circle, n = 9) for the oscillatory characteristics period (a), amplitude (b), phase (c), and the quality control parameter wavelet power (d) at the time point of maximal wavelet power (48.817 h after dexamethasone synchronization). The dashed line in (d) represents the minimal wavelet power threshold of 30 to be considered a “true” oscillation. Wavelet power values of all samples were above this threshold classifying them as “real” oscillations.
