AUC. Area under the curve; pAUC, partial area under the curve, FOBT. Fecal occult blood test; CALB, calgranulin B.

*Sensitivity when the specificity of the model developing samples is set at closest to 90%.

**Observed specificity closest to 90%.

***Partial AUC for specificities range from 90% to 100%.
