Outcomes
Primary Outcome Measures
Number of New Osteoporotic Fractures
Number of new osteoporotic fractures. All fractures which occurred without high impact trauma (i.e. atraumatically, minor accidents and falls from standing height and lower) were regarded as osteoporotic fractures, except for fractures of fingers, face, skull and toes.
Secondary Outcome Measures
Mortality
Number of deaths
Combination of New Osteoporotic Fractures and Deaths
Number of participants with a new osteoporotic fracture or death

5. Study Description
Brief Summary
The purpose of this study is to evaluate the efficacy and safety of bisphosphonates in long term treatment of osteoporosis.
Detailed Description
Is a continued treatment with alendronate for another two years after a preceding therapy with bisphosphonates of at least four years able to reduce the incidence of new osteoporotic fractures in patients at high fracture risk compared to a therapy-free interval?
