Relation between the WWI and the incidence rate in log scale learned by the full mixed effects model (Model 2). Montpellier relation greatly deviates from the average one. The significant deviation in intercept for Montpellier is probably due to an insufficient coverage of the French territory by the relative laboratory of this WWTP. Note that this laboratory is also the only one to provide quantified results by dPCR. The WWTP of Paris Seine-Amont was used for the comparison with the Grand Paris incidence rate.
