  • a Data are from all sites combined. Comparisons between quantitative data were performed using Pearson's correlation coefficient and are reported as r. Comparisons between the quantitative data set and the binary data set were performed using binary logistic regression and are reported as Nagelkerke's R2. Only correlations in which P values were <0.05 are noted. NS, nonsignificant correlations. No significant relationships with adenovirus were observed in the Avalon Beach samples. HPyVs, human polyomaviruses detected by qPCR; H-Bac, human-associated Bacteroides marker.
