Figure 5. Scatter plots of the natural log of cholera incidence/10,000 population versus potential predictors among 45 wards in Dar es Salaam, Tanzania.

As the presence of roads was a categorical predictor, it was not included here. Pearson's correlation coefficient between each variable and the natural log of cholera incidence/10,000 population is indicated. * p<0.05, ** p<0.01, *** p<0.001
