| Diagnosis | Diagnostic Tool | AUC (95% CI) | Comparison of AUCs between (p-Value) | |||
|---|---|---|---|---|---|---|

AD, atopic dermatitis; sIgE, specific immunoglobulin E; BAT, basophil activation test; AUC, area under the receiver operating characteristic curve. * p < 0.05 for comparison of AUCs using the Delong method.
