Fig. 2

The top panel represents the dot plot of individual respiratory reactance (Xrs) in the two groups: infants receiving surfactant < 24 h from birth (on the right) and those who did not (on the left). The bottom panels represent the area under the receiver operating characteristic curve (AUC-ROC) of Xrs for predicting surfactant administration < 24 h (bottom-left panel) and sensitivity and specificity of Xrs at different values (bottom-right panel). The best-identified cut-off of Xrs was − 33.4 cmH2O*s/L
