Table 3 The mean characteristics of households that were in clusters of high or low densities of Anopheles gambiae s.l. and Anopheles funestus

From: Geographic coincidence of increased malaria transmission hazard and vulnerability occurring at the periphery of two Tanzanian villages

  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).
