Table 9.

Multivariable random-effects negative binomial models for relationship between daily total captured cough counts (in 3 waiting areas only) and total clinical influenza tests. Model adjusted for total population in waiting areas, day-of-week effects, and clustering by waiting area and calendar date.

Total Influenza tests	IRR	p-value	95% CI
Daily cough count	1.0026	<0.001	1.0017 - 1.0034
Waiting area
Walk-In 1	(reference)	-	-
Walk-In 2	1.62	<0.001	1.28 - 2.03
Pediatric	1.84	<0.001	1.38 - 2.44

Note: IRR = Incidence rate ratio.
