PICRUSt predictive functional profiling (KEGG databases at level 3) between the A–N– and A–N* groups (Table S3), the A–N– and A + N+ groups (Table S4), the A–N– and A + N* groups (Table S5), the A + N– and A + N* groups (Table S6), the A + N– and A + N+ (Table S7), the A + N* and A + N+ groups (Table S8). Table S9: 32 predictive functional categories which differed significantly between any two of the A − N−, A − N*, A + N−, A + N* and A + N+ groups (XLSX 43 kb)
