Randomized Controlled Trial
[Predictive value of ultra-sound densitometry as a method of selective screening for osteoporosis in primary care].
To determine the cut-off point of calcaneous quantitative ultrasound densitometry (QUS) as a selection method in primary care for referral of postmenopausal women for dual energy x-ray absorptiometry (DXA). ⋯ Given its high NPV, QUS can be considered a useful device for screening before DXA. Its low PPV means it has to be combined with other complementary or substitutive selective screening methods, such as predictive rules, which should be evaluated in each specific use.
