Figure 1From: Bacterial diversity and Clostridia abundance decrease with increasing severity of necrotizing enterocolitis Relative abundance of taxonomic differences between NEC stool specimens and controls. Relative abundance of the most abundant taxa at class level (A-C) for NEC specimens (n = 21) compared to controls (n = 74) as well as the abundance at the different severities of NEC (D-F). Clostridia was significantly reduced in NEC patients (C), and as the severity of NEC decreased, the abundance of Clostridia increased. Lethal NEC, n = 6; severe NEC, n = 7; and mild NEC, n = 8. The solid line represents the mean, and the standard deviation is represented by dashed lines when between 0 and 100. (A-C) Significance was determined using a Mann-Whitney U test. For comparison of the NEC levels, Kruskal-Wallis test was used from (D-F). *P value < 0.05, **P value < 0.01. NEC, necrotizing enterocolitis.Back to article page
