Baseline characteristics of data included for exploration of resistance prevalence in BSIs across Europe for 15 antibiotics across 8 bacteria in 29 countries for 2015–2019.

The split of the susceptibility results by country is given in Table A2 in S1 Appendix. The definition of an “antibiotic” was linked to the data given so is at different levels (e.g., separate aminoglycosides were included as well as an antibiotic category of “aminoglycoside”). Fluroquinolones resistance was labelled the same across species though there were species-specific definitions. Age given in years. MRSA covers oxacillin and cefotoxin. 3G = third-generation. Pip-taz = piperacillin-tazobactam. SD = standard deviation.
