Fig. 2 — Direct Comparison of Workflow Performance and Sensitivity: Sample extracts that had been diluted at a 1:2 dilution in AE buffer were analyzed in parallel using RT-ddPCR (black dots) and RT-qPCR (grey dots) by the processing group at IMS. N2 concentrations are presented as log transformed copy numbers per liter of influent filtered. A qualitative comparison between workflows resulted in a ĸ value of 0.314 with overall an overall agreement of 73.8%. Spearman rank correlation analysis resulted in a ρ value of 0.717.
