Comparisons were adjusted for sex, partial pressure of arterial carbon dioxide, perinatal insult score, vasopressor use, and presence of electroencephalographic seizures. The analyses were also adjusted for multiple comparisons using Bonferroni corrections. Bold values are statistically significant p-values (p-values < 0.05).

MAP, mean arterial blood pressure; MAPopt, optimal mean arterial blood pressure; wHVx, wavelet hemoglobin volume index; AUC, area under the curve.
