Overall comparison test for observed AUC=0.002.
Individual AUROC comparisons: clinical gestalt vs all scores, p>0.05.
To calculate the relative mean difference, some scores (those not based on 100 points) were converted to a percentage in the following manner: (patient score/maximum possible score)×100.
AUC, area under the curve.
