Fig. 3: Association between drinking water contamination and self-reported anticipated harm from drinking water.
From: Self-reported anticipated harm from drinking water across 141 countries
Percentage of the population in 23 countries who anticipated harm from their drinking water in the next two years (measured in 2019), by the percentage of the population estimated to be using drinking water contaminated with Escherichia coli at the point of use (measured between 2012 and 2019). Data are presented as observed values (circles) and predicted values (black line) with associated 95% confidence intervals (gray area) based on a fitted weighted least squares regression with robust standard errors. The statistical test was two-tailed.
