Figure 1

Sensitivity analysis on priority setting for intervention by prevalence of HCV in the household and perception of HCV severity in the short run. The Figure shows the predicted proportion of household heads ranking HCV and unsafe water as the first priority for intervention with variation of the household prevalence of diseases related to HCV (from 7% to 45%),[21] and the perception of HCV severity in the short run (fixed at observed mean or +1 Standard Deviation). All other explanatory factors of priority setting selected in the multivariate model (Table 4) were fixed at mean observed values (n = 2,603). The proportion of household heads ranking improved outdoor air quality as the first priority is complementary and it is not shown. Vertical bars show 95% confidence interval of the proportion.
