Additional analyses and extended observations are now available on 50 women from the NaF group followed for up to 6 years of treatment. In these women, LS-BMD increased linearly over the 6 years (median rate, 8.7%\/year or 0.063 g\/cm2\/year). Because during the 4 year trial the NaF dosage was decreased (because of side effects) in 54 of the 101 women randomized to NaF, dose-response relationships could be evaluated. For the entire study population, serum F level correlated directly with increase in LS-BMD (r = 0.61, P &amp;lt; 0.001). When individual person-years of observation were grouped by deciles of LS-BMD, VFR (per 100 person-years) decreased to a nadir of 24 as mean LS-BMD for the group increased from 0.6 to 1.2 g\/cm2 and then doubled to 52 in the group with mean LS-BMD of 1.6 g\/cm2. Multivariate analyses and inspection of three-dimensional plots revealed a complex pattern in which VFR was influenced by interaction of several variables. When the effects of LS-BMD, changes in LS-BMD, and serum F were assessed simultaneously, VFR was seen to decrease with increasing LS-BMD except when the higher LS-BMD was associated with rapid rate of increase in LS-BMD or a large increase from baseline serum F. For some patients (noncompliers or nonresponders), serum F or LS-BMD failed to increase. Thus, it is possible that lower dosages of NaF produce moderate decreases in VFR.<\/jats:p>","DOI":"10.1002\/jbmr.5650090216","type":"journal-article","created":{"date-parts":[[2010,2,3]],"date-time":"2010-02-03T11:29:07Z","timestamp":1265196547000},"page":"265-275","source":"Crossref","is-referenced-by-count":125,"title":["Clinical trial of fluoride therapy in postmenopausal osteoporotic women: Extended observations and additional analysis"],"prefix":"10.1093","volume":"9","author":[{"given":"B.L.","family":"Riggs","sequence":"first","affiliation":[{"name":"Endocrine Research Unit, Division of Endocrinology, Metabolism, and Internal Medicine, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.M.","family":"O'Fallon","sequence":"additional","affiliation":[{"name":"Section of Biostatistics, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Lane","sequence":"additional","affiliation":[{"name":"Section of Biostatistics, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.F.","family":"Hodgson","sequence":"additional","affiliation":[{"name":"Endocrine Research Unit, Division of Endocrinology, Metabolism, and Internal Medicine, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.W.","family":"Wahner","sequence":"additional","affiliation":[{"name":"Section of Diagnostic Nuclear Medicine, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Muhs","sequence":"additional","affiliation":[{"name":"Endocrine Research Unit, Division of Endocrinology, Metabolism, and Internal Medicine, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Chao","sequence":"additional","affiliation":[{"name":"Biomechanics Laboratory, Department of Orthopedics, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"III","given":"L.J.","family":"Melton","sequence":"additional","affiliation":[{"name":"Section of Clinical Epidemiology, Mayo Clinic and Mayo Foundation, Rochester, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1994,2,1]]},"reference":[{"key":"2024013113131233700_bib1","first-page":"366","volume-title":"Bone and Mineral Research, Annual 2.
