During the first 6 hours after the enrolment, infants who will later develop NEC (NEC group) had significantly higher urinary I-FABP, L-FABP, TFF-3, and SAA when compared with healthy infants and higher levels of I-FABP and L-FABP than those who will later develop sepsis (sepsis group) (Figure 1(a)). This evidence concerns the gene FABP1 and necrotizing enterocolitis.
