Table 1.
Access, use, and ownership of ITNs by survey.
Figure 1.
Ownership, access and use of ITNs for all datasets.
Survey results are ordered by ownership. Previously, the visual gap between ownership (blue line) and use (green line) made it seem as though the use gap was vast. When use is compared to access (red line), however, a much closer relationship – and narrower gap – is immediately apparent.
Figure 2.
Population with access to an ITN within the household compared to ownership of at least one ITN.
Blue dots represent the data points for data sets, the blue line the regression function (fitted values). Shaded area is the 95% confidence interval of the fitted values of population with access to an ITN within the household. Red dashed line represents the equity line where ownership is equal to access. On average, population access was 32% lower than household ownership.
Figure 3.
Relationship of ITN use to ITN access.
The figure illustrates the linear relationship of use to access. The red dots are proportion of the population that used an ITN the previous night from the survey datasets. The blue line represents the regression line (fitted values). The shaded area is the 95% confidence interval of the fitted values. The red dashed line represents the equity line, where use equals access. On average, 89% of those with access used a net the previous night.
Figure 4.
Ratio of use to access by access to an ITN within the household.
The ratio of use to access is plotted in red dots, by access. The top red dashed line represents the threshold of 100% use among those with access; the lower dashed line represents a nominal minimum target of 80% use among those with access. The blue line is the fitted values indicating the positive linear relationship between the use to access ratio and access. As access (x-axis) increases, use also increases.
