Figure 1 - Flow chart of case selection from PREDICT
study according to eligibility criteria.
Figure 2 - ROC curve for classifying adequacy of calcium
intake and model performance measures for the selected prediction
modelSubscript: Area under the curve 0.858, Brier score 0.136
Figure 3 – Calibration plot for the selected prediction
modelSubscript: Hosmer and Lemeshow statistic p=0.499. The number of
participants with intake ranges corresponding to the predicted
probability on the horizontal axis is represented by the size of the
dots.
Figure 4 – Screening tool based on the prediction model for
having an adequate calcium intake with color coding for high (red),
medium (orange) and low (green) risks of having an inadequate calcium
intakeSubscript: User instructions: choose the block corresponding with
the intake of cheese. From there, combine the intakes of milk and
yogurt/curd as a cross table to find the predicted probability of having
an adequate calcium intake and color coded risk score of having an
inadequate intake.
