To the Editor: Ms Cadarette and colleagues1 compared the diagnostic properties of 4 different
decision rules and the North Osteoporosis Foundation guidelines for selecting
postmenopausal women for DXA testing, and estimated their sensitivity and
specificity in the detection of low bone density. The diagnostic approaches
mainly relied on age and body weight, with older age and lower body weight
resulting in the highest probability of a obtaining a DXA scan indicating
osteoporosis. This approach, although simple, appealing, and apparently efficacious,
is limited by technical concerns.
