FIG 2.
Recovery for human mastadenovirus (AdV), crAssphage (CrAss), influenza A/B virus (Flu-A/B), measles virus (MeV), murine norovirus (MNV), SARS-CoV-2 (N1), norovirus GII (NoVGII), bacteriophage phi6 (Phi6), pepper mild mottle virus (PMMoV), and rotavirus (RoV) as a function of starting volume of wastewater. Data derived from all concentration methods. (a) All recovery results combined. (b) Recovery separated by virus with a variable y scale (recovery percentage). (c) Existence of any significant differences in the tested volumes. (To analyze which volume is significantly better for viral recovery, panel c is to be analyzed in conjunction with panel ‘a and panel b). The P values (Holm adjustment method) of pairwise comparisons were calculated between extraction volumes with two sample t tests with pooled standard deviations (***, P < 0.001; **, P < 0.01; *, P < 0.05). Comparisons were made with an ANOVA after log10 transformation of recovery, followed by pairwise t tests; Pairwise comparisons found significant differences between all volumes with the Holm adjustment method (P < 0.05).
