ROC curve of Neutrophil count and PCT for children with Influenza A(< 4 years). When the detection of PCT alone, the area under the ROC curve was 0.649 (95% CI: 0.564–0.734; P < 0.05). When the detection of Neutrophil count alone, the area under the ROC curve was 0.692(95% CI: 0.611–0.773; P < 0.05). When the combined detection of them, the area under the ROC curve was 0.779 (95% CI: 0.707–0.851; P < 0.05)
