Summary table of metrics obtained in study.

	Regression analysis			Phylogenetic clustering analysis		K-means analysis
	Slope equation	R 2	Pearson’s correlation coefficient	Range of BGI values across outbreaks	Range of CCC values across outbreaks		Range of maximum silhouette scores for K = 2 across outbreaks (Pearson’s R for K = 2)	Range of average silhouette widths for outbreak isolate groups	Range of average silhouette widths for sporadic isolate groups
cgMLST vs. hqSNP	y = 0.58x + 0.18	0.88	0.94	0.60–0.97	0.97–1.00	cgMLST	0.81 (0.92)–0.99 (1.00)	0.91–0.99	0.21–0.96
wgMLST (chrom)* vs. hqSNP	y = 0.74x + 0.39	0.91	0.95	0.60–0.95	0.99–1.00	wgMLST (chrom)*	0.78 (0.93)–0.99 (1.00)	0.88–0.99	0.16–0.93
cgMLST vs. wgMLST (chrom)*	y = 0.77x + 0.09	0.95	0.98	0.90–1.00	0.97–1.00	hqSNP	0.79 (0.94)–0.99 (1.00)	0.87–0.99	0.31–0.96

wgMLST (all loci) was excluded from regression analysis, phylogenetic clustering comparisons, and K-means analysis; only wgMLST(chrom) was used.
