Treatment of osteoporosis generally is guided by dual energy x-ray absorptiometry (DEXA)-measured T-scores. More recently, models have been developed to predict 10-year fracture risk. In this population-based study that involved nearly 6000 women in Manitoba, Canada, researchers evaluated physician prescribing of medications for osteoporosis in 2005, when physicians received only DEXA–measured T-scores, compared with 2006, when physicians also received 10-year absolute fracture risk information based on a freely available web-based calculator. T-scores were categorized as normal, osteopenic, or osteoporotic. Ten-year absolute fracture risk was categorized as low (<10%), moderate (10%–20%), or high (>20%). During 2 years of follow-up, the in…
