Ten-year probability of a major osteoporotic fracture (%) by age at the intervention threshold and lower and upper assessment thresholds calculated with FRAX for Singapore adjusted for ethnicity
| Age (years) | Intervention thresholda (%) | Lower assessment thresholdb (%) | Upper assessment thresholdc (%) |
|---|---|---|---|
| 40 | 1.51 | 0.65 | 1.81 |
| 45 | 1.95 | 0.85 | 2.34 |
| 50 | 2.96 | 1.32 | 3.56 |
| 55 | 4.94 | 2.26 | 5.93 |
| 60 | 8.35 | 3.95 | 10.02 |
| 65 | 13.07 | 6.51 | 15.68 |
| 70 | 19.87 | 10.68 | 23.85 |
| 75 | 25.67 | 14.99 | 30.80 |
| 80 | 28.53 | 18.24 | 34.23 |
| 85 | 31.66 | 20.81 | 37.99 |
| 90 | 31.79 | 21.08 | 38.15 |
aThe threshold is the probability of a major osteoporotic fracture for a woman with a previous fracture and no other clinical risk factors without BMD
bThe lower assessment is the probability of a major osteoporotic fracture for a woman with no clinical risk factors without BMD
cThe upper assessment was set at 1.2 times the intervention threshold
