Figure 2: Treatment with guaifenesin significantly reduced fetal weight (a), fetal length (b), fetal skull length (c), fetal tail length (d), forelimb length (e), and hindlimb length (f) as compared with control group. Data are represented by a mean ± standard error of the mean, where n = 5. *P < 0.05, **P < 0.01, and ***P < 0.001 represent comparison with control group
