Comparison of mean ABW and mean EFWs by ultrasonography methods.

	N	Mean (s.d.)	Minimum	Maximum	Paired t	value
ABW	100	2740.35 (354.19)	2000	4200
EFW by Hadlock	100	2740.44 (353.23)	1847	4145	−0.008	0.994
EFW by Shepard	100	2716.05 (332.38)	2089	4050	2.42	0.017

s.d., standard deviation; ABW, actual birth weight; EFW, estimated fetal weight.
