Fracture group included participants with new fractures during the 5 year follow-up visit. Fracture consists of non-vertebral fracture and vertebral fracture, which were investigated by questionnaire survey and lateral radiographs, respectively.
Non-fracture Group
n=864 Participants
Non-fracture group included participants without new fractures during the 5 year follow-up visit. Fracture consists of vertebral fracture and non-vertebral fracture, which were investigated by questionnaire survey and lateral radiographs, respectively.
