Detailed Instructions: In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
Q: Context: Both the FRAX and Garvan calculators are used to estimate absolute risk of fracture, but they sometimes produce different estimates. We sought to determine which patient characteristics contribute to these discrepancies.', 'Ten-year hip fracture risk was estimated for 122 women, using both FRAX and Garvan with bone mineral density (BMD).', 'Differences in estimates of hip fracture were assessed, both in absolute terms and with respect to a treatment threshold of 3%.', 'Garvan estimates were higher than FRAX estimates across the range of ages and BMDs studied. A history of falls or of multiple fractures increased risk calculated by Garvan 3-6-fold, but did not account for all differences between calculators. Discrepancies around a 3% treatment threshold occurred in 31/122 (25%). Women aged 70-74 years, and women with osteopenia were most likely to have discordant estimates. Most discordant estimates (29/31) had a Garvan estimate 3% and FRAX<3%. Falls, multiple fractures, ethnicity and a history of parental hip fracture contributed to some discordant estimates.\Question: Does reasons for discrepancies in hip fracture risk estimate using FRAX and Garvan calculators?
A:
Hip fracture risk estimates are usually higher with Garvan than FRAX, and these differences could impact on treatment decisions in about a quarter of patients. Falls and multiple fractures have a strong influence on Garvan risk estimates, when present. Clinically important discrepancies tend to occur in patients who are at borderline fracture risk. In patients with hip fracture risks near the treatment threshold with one calculator, use of the other calculator should be considered to help guide treatment decisions.
