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.
