Fetuses in the high-dose group exhibited markedly lower weight (−0.107 ± 0.040 g, P = 0.016) and crown-rump length (−3.159 ± 0.262 mm, P < 0.001) compared with controls, while the mid-dose group showed a nonsignificant trend for reduced weight (−0.056 ± 0.036 g, P = 0.139) and significantly reduced length (−1.534 ± 0.236 mm, P < 0.001).
