P-values of the statistical models for glyphosate isopropylamine salt pure (GLY) (multivariable analysis of variance) and in Roundup LB plus (RU) (multivariable proportional-odds ordinal regression).

GLY		P-value		RU		P-value
Comparison of		Model A	Model B	Comparison of		Model A	Model B
Recent isolates	Historic isolates	0.726	–	Recent isolates	Historic isolates	0.293	–
Pathogenic E. coli	Commensal E. coli	–	<0.001	Pathogenic E. coli	Commensal E. coli	–	0.314
Non-ESBL	ESBL	0.013	0.035	Non-ESBL	ESBL	0.443	0.479
Poultry	Pig	<0.001	<0.001	Poultry	Human	0.031	–
Poultry	Cattle	0.01	0.002	Poultry	Pig	–	0.001
Pig	Cattle	0.608	0.229	Poultry	Cattle	–	0.002

Model A investigates the time point of isolation, the ESBL-status and the host, Model B (without the ECOR collection) investigates the following categories: pathogenic or commensal, the ESBL-status and the hosts (poultry, pig, and cattle). Statistically significant P-values <0.05 are shown in bold. Group with higher minimum inhibitory concentrations are underlined.
