[Retracted] Effects of Pulmonary Surfactant Combined with Noninvasive Positive Pressure Ventilation on KRT-14 and ET-1 Levels in Peripheral Blood and Therapeutic Effects in Neonates with Respiratory Distress Syndrome

Figure 2

Levels of KRT-14 and ET-1 before and after treatment. (a) There was no significant difference in KRT-14 between the observation group () and the control group () (, ). KRT-14 in both groups was significantly decreased after treatment (), and it in the observation group () was significantly lower than the control group () (, ). (b) There was no significant difference in ET-1 between the observation group () and the control group () (, ). ET-1 in both groups was significantly decreased after treatment (), and it in the observation group () was significantly lower than the control group () (, ). denotes .
