Effects of pulmonary surfactant combined with noninvasive positive pressure ventilation in neonates with respiratory distress syndrome

Figure 3 Diagnostic value of the curative effectiveness of keratin-14 and endothelin-1. A: Keratin-14 was significantly lower in neonates with effective therapy (2.94 ± 0.56) than in neonates with ineffective therapy (3.70 ± 0.65) (t = 5.472, P < 0.001); B: Endothelin-1 (ET-1) was significantly lower in neonates with effective therapy (33.80 ± 5.36) than that in neonates with ineffective therapy (42.68 ± 4.48) (t = 6.997, P < 0.001); C: Receiver operating characteristic (ROC) curves of keratin-14 in the diagnosis of effective therapy; D: ROC of ET-1 in diagnosis of therapeutic effect after treatment.
