Fetal biometric growth parameters, expressed as gestational age-specific percentiles, assessed during the third trimester in alcohol-exposed and comparison pregnancies

Parameter	Alcohol exposed (n = 47)^*	Comparison (n = 31)^*	P (unadjusted)	P (adjusted)^†
Estimated fetal weight	30.3 ± 16.4	32.9 ± 17.6	NS	NS
Biparietal diameter	53.6 ± 30.2	69.8 ± 27.6	< 0.05	< 0.05
Head circumference	44.5 ± 25.4	50.3 ± 22.9	NS	NS
Abdominal circumference	46.8 ± 26.5	56.3 ± 24.2	NS	NS
Femur length	47.1 ± 27.8	45.5 ± 24.9	NS	NS

Values are mean ± SD percentiles.

Sample size might vary owing to missing values.
