Concordance of typing techniques using the adjusted Wallace coefficient for nonoutbreak (ABBL) CRAB and outbreak (ABOB) CRAB isolates

Typing methoda	Adjusted Wallace coefficient (95% CI)b
	PFGE	MLST	WGSc
PFGE		0.462 (0.228–0.696)	0.136 (0.087–0.186)
MLST	0.122 (0.038–0.205)		0.041 (0.000–0.091)
WGSc	0.882 (0.841–0.923)	1.000 (1.000–1.000)

^aPFGE, pulsed-field gel electrophoresis; MLST, multilocus sequence typing; WGS, whole-genome sequencing.

^bCI, confidence interval.

^cIsolates were considered the same type by WGS if there were ≤2 single nucleotide polymorphisms between them.
