Figure 1.

Distribution of key input price variables in 2019 international dollars (I$). Red square with bars denotes I$ mean and 95% CI. Blue dots denote datapoints. ‘Promotion (base)’ is the base case intervention including one-to-one activities, group activities and mass media. ‘Promotion (alternative)’ is the case excluding one-to-one activities. This figure presents results in I$, to illustrate the shape of data from which means were calculated, and which are directly comparable. Median US$ prices per household after converting to local purchasing power are US$33.9 for base case promotion, US$14.8 for HWF, US$14.8 for soap expenditure and US$19.4 for alternative case promotion. Median annual expenditure per household on water for handwashing was US$5.7 in rural areas and US$4.0 in urban areas. The US$ median for the home-made HWF considered under sensitivity analysis was $1.2. HWF, handwashing facility.
