  1. a proportion of respondents out of the overall 64 CORPs interviewed
  2. b out of those habitats that were recorded as wet by the CORPs during their routine surveys
  3. The probability of mosquito larvae detected by the CORPs modeled with a binary distribution and logit link function using Generalized Estimating Equations (GEE) excluding time spent to get to the field (P = 0.608), Who individuals were recruited by (P = 0.521) and clear knowledge of project goal (P = 0.654).
  4. c Reference group for particular variable, CI: confidence interval, CORPs; Community-owned resource persons
  5. N: the number of habitats that were reported wet by CORPs during routine habitat surveys and contained larvae during the cross-sectional surveys
  6. n: the number of habitats where CORPs found larvae during their routine habitat surveys,
  7. NA: Not applicable
