Table 6 Mixed-effects regression IRR values, the two boundaries of the 95% CI (IRR 2.5% and 97.5% CI) and the P value, for each predictor included in the final model of household female Aedes mosquito density for the dataset from Posadas, Argentina

From: Determinants of Aedes mosquito density as an indicator of arbovirus transmission risk in three sites affected by co-circulation of globally spreading arboviruses in Colombia, Ecuador and Argentina

  1. Estimation of model coefficients was conducted on a total of 92 households (25% of the full dataset). Average proportion of variance explained by random-effects factors, i.e. month and neighborhood, was 0.16 and 0.00, respectively
  2. aPredictors that are underlined have an IRR that is significantly different from 1
  3. *Significant at a threshold α = 0.05
