Table 2. Association between presence of ISMav6 and antibiotic resistance.

Drug susceptibility test	Detection of ISMav6		P-value for trend test
	ISMav6 (+)	ISMav6 (-)	ISMav6 (+) vs. ISMav6 (-)
CLR			0.375
S	42	27
I	1	0
R	2	0
MXF			0.003
S	17	17
I	9	9
R	18	1

Data are presented as numbers.

Because drug susceptibility testing was not performed in all patients, the sum of the individual categories is less than 92.

Definition of abbreviations: CLR = clarithromycin; MXF = moxifloxacin; S = susceptible; I = intermediate; R = resistant.
