Prevalence of Fracture Risk Factors in Postmenopausal Women Enrolled in the POSSIBLE US Treatment Cohort
Table 4
Self-reported on-study fracture among pharmacologically treateda POSSIBLE US subjects stratified by the National Osteoporosis Foundation treatment thresholds.
Number of subjects with FRAX score
FRAX predicted 10-year risk of ≥3% for hip fracture
FRAX predicted 10-year risk of ≥20% for major osteoporotic fracture
FRAX score ≥ intervention threshold for either hip or major osteoporotic fractures
