Over the three-year period, risedronate produced greater reductions in fractures compared to alendronate. Patients treated with risedronate experienced 23 hip and 111 vertebral fractures (134 total fractures) per 1,000 patients (Table 3). In contrast, a total of 28 hip fractures and 115 vertebral fractures per 1,000 patients (for a total of 143 fractures) were experienced [...]

Vertebral Fracture As with hip fracture, vertebral fracture rates for the general population were adjusted to reflect a PMO population. Efficacy values (in terms of relative risk of fracture) of 0.51 and 0.53 were used for patients treated with risedronate tablet or alendronate, respectively. These efficacy rates were obtained from randomized clinical trials with similar [...]
