Figure 1. The BMD of lumbar vertebrae 2–4 (L2-L4) of the four groups.

Figure 1

Comparison of bone mineral density (BMD) of lumbar vertebrae 2–4 (A:L2, B:L3, C:L4) 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. The x-axis represents time after surgery (weeks). 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.
