From: Doppler and birth weight Z score: predictors for adverse neonatal outcome in severe fetal compromise

Outcome variable Significant variable F test p-value Excluded variables
Mortality -Birth weight Z score 12.33 0.001 -Absent or reversal end diastolic flow in umbilical artery. -Abnormal ductus venosus S/A ratio -Absent or reversal flow during atrial systole in ductus venosus.
Severe Morbidity -Birth weight Z score 8.26 0.006 -Absent or reversal end diastolic flow in umbilical artery. -Abnormal ductus venosus S/A ratio. -Absent or reversal flow during atrial systole in ductus venosus
