Extended Data Fig. 5: Significantly different KO functional categories that were significantly enriched in the anti-PD-1 group or anti-PD-1+acarbose group were separately analysed for KEGG pathway enrichment.

KO functional categories and pathways that were significantly enriched in the anti-PD-1 group were shown in red, and those significantly enriched in the anti-PD-1+ acarbose group were shown in green.
