Comparison of bone mineral density (BMD, g/cm3) of the second, third and fourth lumbar vertebrae (L2BMD, L3BMD, L4BMD) in SHAM, OVX+NS, OVX+E and OVX+iCR groups at 4-, 8- and 12-week postoperation. Data represents the means ± standard deviation (SD ), n = 10 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.
