Adjusted probability¹ of an individual abscess from a steer managed in a natural² or traditional³ program to harbor Fusobacterium, Bacteroides, or Trueperella

Bacterial genus	Natural		Traditional		P-value4
	Probability of presence, %	SE	Probability of presence, %	SE
Fusobacterium5	100.00	NA	100.00	NA	NA
Bacteroides	95.56	3.422	94.71	4.326	0.850
Trueperella	23.82	8.676	4.71	3.316	0.022

Adjusted probability generated by transforming the odds estimated by logistic regression to a probability scale.

Program included no growth-promoting technologies or antimicrobials.

Program included hormonal implants, tylosin phosphate, monensin, ractopamine hydrochloride, and treatment with antimicrobials when necessary.

P-value for the test of the log odds ratio between natural and traditional management programs.

No logistic regression analysis performed given Fusobacterium presence in all liver abscesses; unadjusted prevalence presented.
