Figure 4From: Effect of combined treatment with alendronate and calcitriol on femoral neck strength in osteopenic ratsCortical BMC and BMD at the femoral neck measured by pQCT densitometry. Effects of alendronate (ALN), calcitriol (VitD), and combined alendronate and calcitriol treatments (ALN+VitD) on the pQCT densitometric parameters of cortical BMC and BMD at the femoral neck in OVX rats after 12 weeks of treatment are shown. The data are presented as mean ± SD (n = 6 per group). ### P < 0.001 as compared with corresponding values in saline-treated OVX (unpaired t-test). * P < 0.05, ** P < 0.01, *** P < 0.001 as compared with corresponding values in saline-treated OVX (Tukey's multiple comparison test). Cortical BMC was significantly lower in the saline-treated OVX than in the sham group. Cortical BMC in OVX rats was significantly improved by alendronate, calcitriol single treatment, and the combined treatment.Back to article page
