The mean actual birth weights and mean fetal weight measured by clinical and ultrasound methods.

	N	Mean ± S.D.	Minimum	Maximum	t-test	P value
Actual fetal weight	200	3,242 ± 508 g	2,350 g	4,600 g
Clinical fetal weight	200	3,541 ± 633 g	2,381 g	4,924 g	0.453	0.695
Ultrasound fetal weight	200	3,141 ± 441 g	2,270 g	4,590 g	2.259	0.122

P value (P < 0.05) = significant.
