HADS-T, Hospital Anxiety and Depression Scale-Total; PPV, positive predictive value; NPV, negative predictive value; positive utility index (UI+), sensitivity × PPV; negative utility index (UI−), specificity × NPV; Youden index, sensitivity + specificity-1. ^†Bold values signify the balanced cutoff point with the highest Youden index.
