Differences in fecal microbiota constituents of normal-weight, overweight, and obese Shenzhen adolescents. Bacterial taxa at the A phylum, B family, and C genus levels demonstrated significantly different abundances across the three BMI groups. Each bar plot indicates the mean proportion of sequences assigned to a feature in each group. Whiskers represent 1.5* inter-quartile range. Relative abundances were analyzed by Kruskal–Wallis test followed by post-hoc Tukey HSD test (*P < 0.05, **P < 0.01, and ***P < 0.001). N, normal-weight; OW, overweight; OB, obese
