    4. 4. Anti fracture efficacy of the most frequently used treatment of postmenopausal osteoporosis in addition to the effects of calcium or vitamin D supplementation, or both, as derived from placebo controlled randomized trials. Delmas, The Lancet 359:2018-2026, 2002 0 ± Vitamin D derivatives ++ +++ Risedronate 0 +++ Raloxifene ++ +++ PTH 0 + HRT - ± Fluoride 0 + Etidronate 0 + Calcitonin ++ +++ Alendronate Non Vertebral # Vertebral # DRUG
