Faecal bacteria abundances significantly associated with 5‐aminosalicylic acid (5‐ASA) concentration on different taxonomic levels (regression analysis)

Phylum	Class	Order	Family	Genus	P	B
Proteobacteria	Betaproteobacteria	—	—	—	0.004	−2.02
Bacteroidetes	Betaproteobacteria	Burkholderiales	—	—	0.007	−2.02
Bacteroidetes	Bacteroidia	Bacteroidales	Prevotellaceae	—	7.7 × 10−5	−5.17
