Fig. 4.

(a) Mean percentage significant coherence of SctO2 vs. aEEG from 15 newborns with ‘mild’ HIE, 11 of whom had normal MRI outcome (shown in blue) and 4 had abnormal MRI outcome (shown in red) The shaded regions represent the standard errors of mean. (b) For the mild HIE group, statistical difference of SctO2 and aEEG coherence in the selected wavelet scale range of 64–250 min is not significant between the normal MRI vs. abnormal MRI groups. (c) Mean percentage significant coherence from 14 newborns with ‘moderate’ HIE, 12 of whom had normal MRI outcome (shown in blue) and 2 had abnormal MRI outcome (shown in red). The shaded regions represent the standard errors of mean. (d) For the moderate HIE group, the difference of NVC (i.e., SctO2 and aEEG coherence) in the selected scale range of 64–250 min is statistically significant (p = 0.04) between the normal and abnormal groups.
