Table 2.

Pearson correlation coefficients (r) between cases by episode date and wastewater measure on the subset of data from the Warden, Humber AMF, and Kitchener wastewater sampling sites.

Site (n)	Raw N1–N2	PMMoV normalized N1–N2	CrAssphage normalized N1–N2
Warden (32)	0.608^a	0.712^b	0.553^a
Humber AMF (29–31)	0.726	0.696	0.767
Kitchener (57)	0.833^a	0.766^b	0.751^b

Comparisons were done on two overlapping correlations based on dependent groups with the cocor package using 95% confidence intervals (30). Letters indicate significant differences between correlations (p = 0.05).
