Figure 2. Observed Versus Predicted Fracture Probability (%), With and Without BMD, by Quintiles of Fracture Risk.

Figure 2

Figure 2

Squares represent the predicted fracture probability without BMD used in the risk calculator, circles with BMD used in the calculator.

Ten-year fracture risk quintiles:
Hip fracture: Major osteoporotic fracture:
Without BMD: Quintile 1: <1.3% Without BMD: Quintile 1: <4.1%
 Quintile 2: 1.3 to <2.0%  Quintile 2: 4.1 to <5.6%
 Quintile 3: 2.0 to <3.2%  Quintile 3: 5.6 to <7.1%
 Quintile 4: 3.2 to <6.0%  Quintile 4: 7.1 to <11.3%
 Quintile 5: ≥6.0%  Quintile 5: ≥11.3%
With BMD: Quintile 1: <0.9% With BMD: Quintile 1: <3.5%
 Quintile 2: 0.9 to <1.8%  Quintile 2: 3.5 to <5.1%
 Quintile 3: 1.8 to <3.3%  Quintile 3: 5.1 to <7.3%
 Quintile 4: 3.3 to <6.7%  Quintile 4: 7.3 to <11.3%
 Quintile 5: ≥6.7%  Quintile 5: ≥11.3%
