2. Figure 1
The mean birth weight of three groups following term gestation. The mean birth weights of neonates were 3,009.8 ± g, 3,059.6 ± g, and 3,100.7 ± g in fresh embryo transfer (ET) cycles, all Japanese neonates, and frozen-thawed ET (FET) cycles, respectively. The mean birth weight of fresh ET was lower compared with FET and all Japanese neonates. Among the three groups, the mean birth weight of FET was significantly higher (P<.0001) after adjusting for gestational age.
