The statistical significance of a trend was assessed by linear regression analysis. r² values, along with associated two-tailed p-values (in brackets), are shown. Significant (p < 0.05) values are in bold: red (increasing trend) or blue (decreasing trend).

^aST, sequence type.

^bConsidered as the number of intermediate/resistant isolates.

^cND, not determined: virulence score of ST185 isolates was always null.
