One-year changes in hip DXA , NTX , and BAP were not related to subsequent fracture risk , but older age and lower hip DXA at time of discontinuation were significantly related to increased fracture risk ( lowest tertile of baseline femoral neck DXA vs other @ tertiles relative hazard ratio , @ -LSB- @ % CI , @-@ @ -RSB- ; total hip DXA relative hazard ratio , @ -LSB- @ % CI , @-@ @ -RSB- ) .
