Association of RV Detection with Bacteria Quantity¹.

	Bacteria Quantity Detected (CFUe)	RV Detection (%)	p-value
	Bacteria Quantity Detected (CFUe)	RV Detection (%)	vs. no bacteria	vs. lower half/lowest quartile	vs. 2^nd quartile	vs. 3^rd quartile
M. catarrhalis	0	38%	-	-	-	-
	1–202	45%	0.42	-	-	-
	203–161,000	53%	0.07	0.45	-	-
S. pneumoniae	0	35%	-	-	-	-
	1–322	48%	0.03	-	-	-
	323–8,770,000	73%	<0.0001	0.0002	-	-
H. influenzae	0	37%	-	-	-	-
	1–3	34%	0.42	-	-	-
	4–12	42%	0.23	0.11	-	-
	13–79	34%	0.42	0.98	0.10	-
	80–102,000	57%	<0.0001	<0.0001	0.005	<0.0001

0 = below detection. Detectable bacteria were divided into above and below median. Because we detected H. influenzae in a large quantity of samples we divided this group into quartiles.
