Table 3. Results of the analysis using zero inflated negative binomial model (ZINB) model.

Variables	Estimate	Wald 95% CI	P-value
Percent of population living in the urban area	0.0028	-0.0145 to 0.0201	0.75
Percent of households having access to improved sanitation	0.0056	-0.0289 to 0.0401	0.75
Percent of household having access to improved water source	0.0213	-0.0310to 0.0525	0.26
Percent of households living under poverty	-0.0062	-0.0449 to 0.0324	0.75
Distance from center of the district to the nearest waterbodies	-0.0170	-0.0338 to -0.0003	0.045

Note: Each variable was entered in the model in combination with the neighborhood incidence rate to adjust for the spatial structure of the disease. Only the negative binomial component of the model is provided, since the zero inflated component of the model did not converge.
