Predicted probability of mosquitoes with DENV-positive saliva for WT and wMel Ae. aegypti mosquitoes, based on a marginal logistic regression model. Each dot point shows the proportion of all mosquitoes that had DENV in their saliva among all mosquitoes that took a blood meal. The corresponding smoothing curves and shading (representing 95% CIs) illustrate the predicted probability of having virus in saliva between days 8 and 20 postexposure to DENV-1 and DENV-4 serotypes (DENV-2 and DENV-3 were excluded due to the small numbers of patients infected with these serotypes).
