If you read the paper it says that the primary endpoint was total hip areal BMD assessed by DEXA. But Secondary endpoints were BMD of the femoral neck and lumbar spine . The non-inferiority threshold was set at 2%. - The BMD difference in the LS spine was 1.8% so this was also noninferior. But these are BMD results and not long term Fx results that you may be wanting. Its still encouraging.
