Table 2.
Ten-year probabilities of a major osteoporotic fracture (%) in postmenopausal women by age to show the intervention threshold together with the upper assessment threshold and lower assessment threshold, derived using the Kuwaiti FRAX model. Under this scheme, BMD testing would be recommended at probabilities lying between the upper and lower assessment thresholds.
