  1. aClusters of households with high densities of anophelines were identified with Z scores >1.96, or vice versa, clustered households with low densities of anophelines were identified with Z scores < −1.96.
  2. bThe distance of each household from the village centre was calculated using ArcGIS software (ESRI, Redlands, CA, USA).
