Comparison of bone morphometric indicators (relative bone volume (BV/TV), trabecular number (TbN), trabecular spacing (TbSp), and trabecular thickness (TbTh)) of the L3 and femoral distal ends (Femur) in SHAM, OVX+NS, OVX+E and OVX+iCR groups at 4-week postoperation. Data represents the means ± standard deviation (SD), n=6 rats in each group. Compared with SHAM group, a means p<0.05, b means p<0.01; Compared with OVX+NS group, c means p<0.05, d means p<0.01; Comparison between OVX+iCR and OVX+E group, e means p<0.05, f means p<0.01.
