  1. aσ2 is the location-specific unexplained variance
  2. bThe range is the distance at which the spatial correlation becomes less than 5%
  3. cPredictive model: geostatistical multinomial model used to predict S. stercoralis and hookworm mono- and co-infection risk at un-surveyed locations
  4. dDeterminant analysis model: model including only socio-demographic, behavioural and district identification data
