Figure 1. Receiver operating curves of the UCT in the categorization of poorly controlled urticaria (CDLQI ≥6). A) CU at study entry (optimal cut-off: ≤10 [sensitivity=95.5%, specificity=63.3%], AUC=0.82 [95%CI: 0.71, 0.93]). B)CSU at study entry (optimal cut-off: ≤10 [sensitivity=100.0%, specificity=65.0%], AUC=0.86 [95%CI: 0.74, 0.98]). C)CIndU at study entry (optimal cut-off: ≤10 [sensitivity=85.7%, specificity=60.0%], AUC=0.75 [95%CI: 0.50, 100.0]). D)CU in children aged 4 to 16 years at study entry (optimal cut-off: ≤10 [sensitivity=92.9%, specificity=65.4%], AUC=0.79 [95%CI: 0.65, 0.93]). E) CU at follow-up (optimal cut-off: ≤9 [sensitivity=87.5%, specificity=66.7%], AUC=0.81 [95%CI: 0.56, 1.00]).
