Previous and predictive validity: area under the curve (AUC), sensitivity/specificity, positive (PPV) and negative predictive value (NPV), and diagnostic odds ratio (DOR) for each cut-off value in the A-TAC
^aNo previous established cut-off value
^bFor clarity reasons, NPV is reported with three decimals
