Breakdown of cost burden categories. Over 40% of Bolivian families in this study spent at least 1% of their annual income on a single episode of pediatric diarrhea. The black bars represent percentage of patients in each cost burden category. The gray line shows the cumulative percentage of patients in or below the current cost burden category. Each cost burden category, on the X axis, represents a range of one percentage point, for example, 0%=0 - <1%, 1%=1% - <2%. Only pediatric visits with complete cost records and hospital data were analyzed (N=535).
