Table 2 Posterior rate ratio estimates and 97.5% credible interval (CI) for the best fitting model (Model 1) for An. gambiae (s.l.) and An. funestus (s.l.). The model includes all data range (2011–2015) and incorporates the effects of interventions. For the spatio-temporal specification, a parameter for the spatial range of influence is shown
