Figure 3. Survival curves stratified by severity (liver herniation and patch repair). (A) The survival curves of severe congenital diaphragmatic hernia (CDH) neonates who presented with liver herniation or required patch repair. (B) The survival curves of mild CDH neonates who underwent primary repair and did not have liver herniation. The yellow, blue and red curves represent the survival curves of the Group A (<24 hours), Group B (24–48 hours) and Group C (≥48 hours), respectively. The plus sign at the end of each curve represents a censored value.
