The relationship between clinical sample type and gene expression of umuDC.

umuDC	Sample type						P
	Sputum	Blood	Urine	Wound	Endotracheal	Total
No change	1	3	0	1	1	6	0.692 C † NS
Up regulation	2	4	1	1	0	8
Total	3	7	1	2	1	14

C – chi-square test; ^† – more than 20 % of cells have an expected count of less than 5; NS – not significant; p –p-value
