Note:—GW indicates gestational weeks.
↵a Fetal data were compared between trimesters and structures using repeated-measures ANOVA. P values are Bonferroni-corrected for multiple pair-wise comparisons. No statistical comparisons were performed for the adult data.
↵b Significantly different from the second trimester (P < .001).
↵c Significantly different from the brain stem within the same trimester (P < .001).
↵d Significantly different from the cerebellum within the same trimester (P < .001).
↵e Significantly different from the thalamus within the same trimester (P < .001).
