Write answer in between .Q:An investigator is studying the efficacy of a new bisphosphonate analog in preventing hip fractures in patients above 60 years of age with risk factors for osteoporosis but no confirmed diagnosis. Participating patients were randomized to either pharmacologic therapy with the new bisphosphonate analog or a placebo. The results show:Hip fracture No hip fracturePharmacologic therapy 3 97No pharmacologic therapy 10 190Based on this information, which of the following best represents the proportionate reduction in the risk of hip fractures brought about due to pharmacologic therapy, in comparison to the control group?? A: 3, B: 5, C: 40, D: 2, E: 60,  <response>: To calculate the proportionate risk reduction, we first need to calculate the absolute risk reduction ARR. The absolute risk of hip fracture in the control group no pharmacologic therapy is 10200 5. The absolute risk of hip fracture in the treatment group pharmacologic therapy is 3100 3. Therefore, the ARR is 5 - 3 2. The proportionate risk reduction is the ARR divided by the baselinecontrol risk. In this case, it is 25 0.4 40.So the proportionate risk reduction brought about by the pharmacologic therapy compared to control is 40.C: 40
