^a E. faecium isolates in the source categories of hospitalized patients, farm animals, and other sources. Isolates from unknown sources were not included. In total, 1,645 isolates were included in the analysis.

^b Pigs, poultry, veal calves, meat, and milk products.

^c ORs indicate significance of association between E. faecium source categories and BAPS (sub)group and lineage. ND, not done.
