Comparison of cerebral Dopplers in FGR and SGA cohorts.

Number of Abnormal Dopplers in ISUOG Groups	SGA (n = 30)	FGR (n = 51)	p-Value
Total # of abnormal Dopplers † (1 pt each for MCA, ACA, PCA, VA; max: 4 pts/fetus)	4	36	0.055
# of fetuses with ≥1 abnormal cerebral Doppler ‡	4/30	15/51	0.113
# of fetuses with MCA PI < 5th centile ‡	1/30	10/51	0.047 *
# of fetuses with ACA PI < 5th centile ‡	2/27	11/46	0.113
# of fetuses with PCA PI < 5th centile ‡	1/29	7/46	0.141
# of fetuses with VA PI < 5th centile ‡	0/26	8/43	0.021 *

Comparisons of cerebral dopplers were performed with Mann-Whitney U ^† and Fisher’s exact ^‡ tests. Full Doppler information was not available on all 81 patients; thus, the N varies by Doppler study performed as evident above. Abbreviations: MCA: middle cerebral artery; PI: pulsatility index; ACA: anterior cerebral artery; PCA: posterior cerebral artery; VA: vertebral artery. “* indicates statistical significance (* p < 0.05).”
