Association of Mannheimia haemolytica prevalence and Ct values on day 28, mortality, and morbidity (on day 14 and 28) with the presence of Mycoplasma bovis on previous time points.

Outcome	Mb day 0	Mb day 7	Mb day 14
Mh prevalence day 28	n/e	0.45 (0.31, 0.6)*	0.11 (−0.12, 0.33)
Mh Ct values day 28	2.27 (0.46, 4.08)*	−2.89 (−4.2, −1.57)*	−1.2 (−2.92, 0.51)
Morbidity day 14	−0.05 (−0.23, 0.13)	0.1 (−0.02, 0.22)	n/a
Morbidity day 28	−0.08 (−0.14, −0.02)*	0.02 (−0.08, 0.11)	0.003 (−0.1, 0.1)
Mortality	−0.04 (−0.08, 0.003)	0.04 (0.002, 0.08)*	−0.007 (−0.1, 0.08)

Mh, Mannheimia haemolytica; Mb, Mycoplasma bovis presence/absence. Values are predictive margins (prevalence differences or mean differences accordingly) with 95% confidence intervals between parentheses. Asterisk (^*) and boldfaced figures: P-value < 0.05; n/e, not estimable; n/a, not applicable.
