Characteristics of study and non-study districts in Tanzania. Continuous variables are summarised by the mean (range) and categorical variables by the number (%). Variables were either extracted from the national census [16] or from district shapefiles from the Tanzania National Bureau of Statistics (NBS) website [19]. These variables were tested using ordinary least squares regression to assess the best variables for predicting numbers of dogs in districts.
