Fracture risk factors have long been identified as key factors in osteoporosis and fragility fractures. The WHO recommended Fracture risk assessmenttool (FRAX) applies clinical risk factors to assess the absolute risk of osteoporotic fractures in each individual. Our preliminary study suggests that FRAX estimates may underestimate the risk of fractures in the Chinese population. In order to optimize the risk prediction model of osteoporotic fractures, a treatment threshold and its optimal cutting point were initially established based on the data of the health management Center of the Second Xiangya Hospital of Central South University.
