  • Note:—CB indicates cerebellum.

  • ↵a Strength of correlation of fetal and neonatal preoperative volumes (first column); fetal and neonatal postoperative volumes (second column); fetal volumes and neonatal ischemic brain injury (third column). Square indicates moderate correlation (closed square, r = 0.3–0.5; open square r = −0.5 to −0.3). Circle indicates strong correlation (closed circle, r = 0.5–0.8; open circle, r = −0.8 to−0.5).

  • ↵b Result of linear regression analysis with correction for PMA at scanning.

  • ↵c Result of quadratic regression analysis. Correlation coefficient and 95% CI are in the On-line Table.
