LEfSe results on gut microbiomes of preterm infants. a Clustering tree. Different color areas represent different groups. The yellow nodes represent microbial taxa without significant differences between PAT and PAF groups. The red nodes represent microbial taxa that played an important role in the PAF group, and green nodes represent microbial taxa that played an important role in the PAT group. b Histogram showing the distribution of LDA values
