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

Parameter	Alcohol exposed (n = 66)*	Comparison (n = 64)*	P (unadjusted)	P (adjusted)†
Estimated fetal weight	31.8 ± 16.5	34.2 ± 16.1	NS	NS
Biparietal diameter	53.9 ± 28.1	54.0 ± 27.1	NS	NS
Head circumference	37.1 ± 20.1	40.1 ± 17.0	NS	NS
Abdominal circumference	36.0 ± 28.6	43.1 ± 32.7	NS	NS
Femur length	52.6 ± 25.2	64.5 ± 20.8	0.004	0.025

Values are mean ± SD percentiles.
