ANOVA with a mixed linear model.

CFTOE: mean average over	Estimates [%] for mean CFTOE (positive values indicate higher values in subjects without IVH/PVL)	95% confidence interval	P -value
1 h	0.004	−0.001 to 0.009	0.086
30 min	0.005	0.001–0.008	0.012
15 min	0.005	0.002–0.007	<0.001
5 min	0.004	0.002–0.005	<0.001

Outcome variable: mean averages of CFTOE. Independent variable: IVH/PVL. CFTOE, cerebral fractional tissue oxygen extraction; IVH, intraventricular hemorrhage; PVL, periventricular leukomalacia.
