TABLE 5.

Statistical comparison of QPCR and culture analysis methods in which pooled data from experimental room trials (n = 7) were used^a

Sampling method	Flooring material	P value
Swab kit	Vinyl tile	0.000b
	Commercial carpet	0.000b
	Residential carpet	0.000b
	Soiled residential carpet	0.210
Sponge swipe	Vinyl tile	0.074
	Commercial carpet	0.000b
	Residential carpet	0.130
	Soiled residential carpet	0.180

^aStudent t tests were performed for each sampling method and flooring material. 

^bP values less than 0.05 indicate that there was a significant difference between the QPCR and culture analysis methods.
