Using Graph Theory to Assess the Interaction between Cerebral Function, Brain Hemodynamics, and Systemic Variables in Premature Infants

Table 1

Stratification of the neonates into three age groups, based on postmenstrual age (PMA) in weeks. For each group, the number of patients, postnatal age (PNA) of the patients, and propofol dose values administered to the subjects in the group are presented.

	Group 1	Group 2	Group 3
	Extremely preterm	Very preterm	Moderate to late preterm
	<28 weeks	28–31 6/7 weeks	32–36 6/7 weeks
Number of patients	5	13	4
PNA (days)
Median	1	1	1
Range	1-2	1-2	1–3
Dose (mg·kg^−1)
Median	1.0	1.0	2.75
Range	0.5–1.5	0.5–2.5	1.0–4.5
