Multiple end-point measurements of necrotizing enterocolitis (NEC) incidence and severity in piglets. A: Kaplan-Meir graph detailing piglet survival. B: gross NEC score in piglets of advancing gestational age exposed to the NEC protocol. A threshold of 3 in any one segment was considered positive for NEC (dashed line). C: histological NEC score was determined in hematoxylin-eosin-stained tissue sections, and a threshold of ≥2 in any tissue section was considered positive for NEC (dashed line). D: plasma intestinal fatty-acid binding protein (iFABP) concentration in the final plasma sample for piglet groups in response to the NEC protocol. B–D: *P < 0.05, significant differences between groups, and error bars show 95% confidence interval. Data analyzed by Kruskal-Wallis test and Dunn’s multiple comparison test. NS, not significant.
