  1. aSign indicates if high indicator values increase (+) or decrease (−) risk. The sign is derived from the regression analysis. bWeights are derived from the coefficients of the regression analysis. cThese indicators were removed from the analysis as they were not statistically significantly (p-value < 0.05) related to malaria endemicity in the study area.
