1. From: Treatment of Postmenopausal Osteoporosis with Slow-Release Sodium Fluoride: Final Report of a Randomized Controlled Trial
Ann Intern Med. 1995;123(6): doi: /
Figure Legend:
Dependence of individual vertebral fracture rate (IVFR) on baseline L2-L4 bone density (BD) in the groups receiving slow-release sodium fluoride (SR-NaF) and placebo.Top.Bottom.All patients had radiologic evidence of osteopenia. However, six patients (three in each group) had baseline L2-L4 bone density greater than 95% that of a normal 30-year-old woman (mean). Values were probably falsely high because of severe scoliosis in three patients and compression fracture in one patient (which yielded a subnormal vertebral area) and reactive degenerative arthritis and aortic calcification, respectively, in two patients (which added extraskeletal mass).
