A 55-year-old woman has T-score -2.0 at the femoral neck. According to the World Health Organization Fracture Risk Assessment Tool (FRAX), she has a ten-year probability of sustaining a hip fracture of 1.5% and a ten-year probability of sustaining a major osteoporotic fracture of 8.9%. Which of the following statements is true regarding her antiresorptive therapy management?
Antiresorptive therapy should be started based on her T-score
Antiresorptive therapy should be started based on her risk of hip fracture alone
Antiresorptive therapy should be started based on her risk of major osteoporotic fracture alone
Antiresorptive therapy should not be started
Antiresorptive therapy should be started based on her risks of both hip fracture and major osteoporotic fracture
