Figure 2.

Comparison of quantitative evaluations of prediction error in pg/mL (PE), mean percent error (MPE), mean absolute percent error (MAPE), and root mean square error (RMSE) across published models. Dashed lines represent criteria for acceptable model predictions, which are 15% for MPE and 30% for MAPE.41 PRED, population predicted values; POSTHOC, individualized predicted values.
