The review included 14 environmental management interventions such as removing unused water containers and covering used ones and the authors conducted three pooled analyses according to the outcome measure with: 9 interventions reporting BI, 10 interventions reporting container index (CI) and 10 studies reporting house index (HI). Finally, this review included 18 integrated interventions, 13 combined environmental with chemical and 5 environmental with biological. The authors reported pooled effect analyses of combined interventions for all three entomological indices. GRADE suggested that the quality of evidence for integrated vector management was very low. Scores for each of the five GRADE criteria are detailed in Table S2. Erlanger et al. [41] concluded that dengue vector control is effective in reducing vector populations. However, as indicated by GRADE scores, such a conclusion is not supported by the quality of evidence. The main problem is that no consideration was given to study quality or design and the impact of this on pooled effect size. The authors did assess publication bias, and found evidence of it for some analyses, but no attempt was made to adjust the pooled effects. The authors investigated the sources of heterogeneity but only through subgroup analysis for intervention type. Finally, because pooled analyses excluded some studies, the authors did not attempt to investigate if this would bias their conclusions. As entomological parameters (which may or may not relate strongly to health) were assessed, the outcomes were considered to be indirect, which also reduced the validity of the evidence
