OR of detection in cases compared with controls by multiplex PCR in nasopharyngeal swabs, by pathogen, adjusted for age and season (logistic regression)

Pathogen	Adjusted OR	95% CI	P value
Streptococcus pneumoniae	1.7	1.2 to 2.3	0.002
RSV	20.6	9.4 to 45.3	<0.001
Influenza virus	6.1	2.5 to 14.9	<0.001
Parainfluenza virus	4.6	1.8 to 11.3	0.001
Metapneumovirus	4.5	1.3 to 16.1	0.021
No pathogen detected	0.1	<0.1 to 0.2	<0.001

P values were obtained by Wald test.
