Figure 3.

Global calibration plots for the PCE and FRAX study populations, plotting the observed outcomes against the predicted risk for the entire PCE and FRAX test sets. A diagonal red line represents perfect calibration. A smoothed line is fit to the curve, and points are drawn to represent the averages in 10 discretized bins. Histograms are drawn under the curves to illustrate the distribution of predictions.

Abbreviations: PCE – pooled cohort equations; FRAX – fracture risk assessment tool.
