  3. This table shows the detailed sagittal measurements of the thoracic vertebrae (T8–T13) in all groups of bipedal rats. Between T11 and T13, both VBHa and VBHp were consistently shorter in the female and OVX + E2 groups than in the OVX group(p < 0.05), while in the posterior column, the pedicular height (PH) and the interpedicular distance (IPH) were increased in the female and OVX + E2 groups compared to the OVX group (p < 0.05). Both VBHa and VBHp were longer in the Triptorelin group than in the female group, while the PH and IPH were shorter; an opposite trend was observed in the scoliotic spines from the female and OVX + E2 groups between T8 and T10, with longer vertebral bodies for both VBHa and VBHp in the anterior column and shorter PH and IPH in the posterior column than the OVX group (p < 0.05). *p < 0.05 compared with the female group, #p < 0.05 compared with the OVX group
