AORs of GI illness associated with each log₁₀ increase in indicator densities by qPCR

	Enterococcus a		Bacteroidales a
Indicator	Multivariate AORsb	(95% CI)c	Multivariate AORsb	(95% CI)c
Bathers	0.39	(0.05–2.81)	0.57	(0.18–1.74)
Non-bathers	0.53	(0.05–5.23)	0.54	(0.15–1.91)

^aBased on daily averages of log₁₀ indicator parameter measured by qPCR.

^bThe multivariate logistic regression model was used to adjust for age, sex, chronic GI illness, and sand exposure among all beachgoers.

^cCI = confidence interval.
