Statistical graphs of histological findings. (A). New bone, residual graft, and soft tissue area measured by histomorphometry at 4 and 8 weeks after surgery for calvarial bone defects in the rabbit model. Data are presented as the mean ± standard deviation. C group, xenogenic bone grafting only; RIS group, risedronate with xenogenic bone grafting; *, significantly different from values obtained 8 weeks after surgery; a, b, significantly different from values obtained in the other group; the black line indicates the standard deviation. (B). Comparison of h score values obtained from the immunohistochemical staining at 4 and 8 weeks after surgery. Data are presented as the mean ± standard deviation. C group, xenogenic bone grafting only; RIS group, risedronate with xenogenic bone grafting; the black line indicates the standard deviation
