All studies reported Ae. aegypti alone unless indicated otherwise. HI = House Index (% houses with larvae and/or pupae); CI = Container index (% water-holding containers with larvae or pupae); BI = Breteau index (no. positive containers per 100 houses inspected); BI_max is defined as the highest or ‘maximum’ block level BI in a neighborhood; Pupal index = pupae per person/premise defined as no. pupae divided by the number of residents/premises.

Immature vector samples are denoted as: ⧫ larvae only; ▪ larvae and pupae; ⊙ Aedes aegypti & Aedes albopictus combined.

Cells marked ✓ indicate the sampling activity was done.

The Sample spatial unit referred to as ‘P*’ is the ‘premise with cardinal points index’ [34]; ‘N'hood’ = neighborhood.

In the right-hand column, the reported association between vector indices and dengue cases is classed as: ‘+’ positive association; ‘−’ no association; ‘+ −’ ambiguous association; ‘∼’ inconclusive or weak association.

Absence of any entries in cells indicates no data or information was reported.
