a Change in BMD at lumbar spine. In both groups, lumbar BMD values increased significantly from before 2 years to after 1 year of denosumab treatment (P < 0.001). However, BMD values in the non-responsive group did not reach those in the BP-responsive group at 1 year of denosumab therapy (P = 0.080). b Change in BMD at hips. In the non-responsive group, BMD values were significantly decreased (P < 0.001) after 2 years of BP treatment. After denosmab treatment, hip BMD values increased in both groups to a comparable degree (P = 0.709). As a result, BMD values in the non-responsive group were lower than those in the responsive group at 1 year of denosumab treatment (P = 0.065).
