Fig. 4: Sexual dimorphism in pelvic angles.
From: Sexual dimorphism of the human fetal pelvis exists at the onset of primary ossification
a Least squares mean and 95% confidence intervals for sex differences in the iliac crest and subpubic angle. Positive least squares mean values indicate that females exhibit larger measurements. The asterisks and black circles indicate significant differences (P < 0.05). The dataset comprised 72 human fetus specimens. b Scatterplot of the subpubic angle (#21). Blue and red squares indicate the estimated means for males and females in each CRL subgroup, respectively. c Ventral view of the subpubic angle in males (CRL, 71 mm) and females (CRL, 71 mm). Scale bar, 1 mm. CRL crown-rump length.
