<qa>  What is the fracture rate in the RPAH patients previously reported as 17 in the first3. Fracture Events Fracture incidence in the RPAH patients has been previously reported as 17 in the first 6 months post-transplantation. The fracture rate is now probably lower due to improvements in immunosuppressive therapy. It is not anticipated that this study will have sufficient power to detect a significant reduction in fractures however fracture events will be recorded, including reduction in height of vertebral bodies at baseline and 12 months post-transplantation.
