Description: Differential abundances and linear discriminant effect size analysis (LEfSe) of gut microbiota. (D) Cladogram of LEfSe analysis results of post24 + m and age-matched control groups (p24 + m control) on the taxonomic order level. Over-representation of taxa is color-coded in red (p24 + m control) and green (post24 + m). Radiating circle depicts phylum to order level. Bar chart of LDA values with significantly different abundances to order level is shown comparing pre versus post24 + m, and healthy versus post24 +m in (F)
Abundance in Group 1: increased abundance in Post24 + m
