95% confidence intervals (C.I.) and the results of pairwise significance tests of all models’ areas under the receiver operating characteristic curves (AUC), within each chief complaint category (CCC). According to DeLong. Bold numbers indicate non-significant p-values. Significance was evaluated on the 0.05 level
