ECOFFs: epidemiological cut‐off values; EUCAST: European Committee on Antimicrobial Susceptibility Testing; NA: not available.
EUCAST epidemiological cut‐off values available as the Decision 2013/652/EU was drafted (2013). For some antimicrobials, these values have been updated (see below). ‘>’ than the ECOFF, criteria used for determining microbiological resistance.
> 0.125 mg/L was used.
Current ECOFFs 0.25 and 0.5 mg/L, respectively.
For temocillin, the cut‐off value used in the analysis was > 32 mg/L.
