  1. LTC = long term care; NH = nursing home; ICF = Intermediate Care Facility; MDS = Minimum Dataset; FREE = Fracture Risk Epidemiology in the Frail Elderly; BC = British Colombia.
  2. *When results for 2 fracture sites were reported, we only included results of hip fractures.
  3. **Study analysis restricted to subpopulation of long term care residents.
