How does the current FORE model differ from the WHO FRAX™ model?
The FORE model and FRAX™ model use the same input variables, the same base fracture rates, and the same relative risks (multipliers). Both can be applied to men and 4 different ethnicities. Both output the 10-year risk of hip and any one of 4 fractures (hip, wrist, humerus, clinical spine). One major difference is that the FORE model provides a graphic display of risk, comparing it to the expected risk, and categorizing it as low, medium, or high. A second difference is the FRAX™ model performs more adjustments for interactions between variables. Thus, users of these models should get very similar but not identical results.
