Fig. 4: Travel-time inequities.

a National-level travel-time differences between Eswatini (green), Malawi (pink) and Zambia (purple). Urban (red) and rural (blue) differences for b Eswatini, c Malawi, and d Zambia. Dots show the cumulative proportion of individuals traveling for treatment for: one, two, and either 3.5 hours (urban areas) or four hours (rural areas). These are derived from the self-reported travel-time data. Fitted curves are logistic CDFs; shaded regions show 95% confidence bands for these curves.
