  1. Genera with the relative abundance of more than 0.5% are presented as mean and compared between the middle-aged and elderly groups using Wilcoxon rank-sum test. The lower abundant genera are grouped as ‘Others’. * indicates significant difference at a P value of < 0.05. At the genus level, only the presence of species belonging to the genus Coprococcus was significantly higher in the elderly group
