Table 4 Predictive values of the independent correlation factors

From: Clinical characteristics of refractory mycoplasma pneumoniae pneumonia in children treated with glucocorticoid pulse therapy

Independent factors Cutoff value Sensitivity Specificity AUC P-value 95%CI
Neutrophil, % 73.75 0.750 0.900 0.888 0.000 0.831–0.945
CRP, mg/L 44.45 0.550 0.850 0.736 0.000 0.648–0.825
LDH, IU/L 590.0 0.763 0.475 0.611 0.048 0.503–0.719
Fer, ng/L 411.0 0.864 0.682 0.814 0.000 0.736–0.892
  1. P value: the AUC value of the independent factors compared to ROC curve reference value 0.5
  2. AUC Area under the ROC curve, Cut-off value The value on the ROC curve is closest to the upper right to take maximum sensitivity and specificity
