Example of sensitivity in cross-country comparisons to the choice of the threshold, observed through dominance.

Each line represents a pairwise comparison of the incidence rates of catastrophic health expenditures between Country A and Country B. Countries are ordered by decreasing proportion of the population reporting any OOP. Solid bars indicate Country A dominance as it exhibited lower incidence rates of catastrophic health expenditures compared to Country B for the range of thresholds shown on the horizontal axis. Dashed bars indicate Country B dominance as it exhibited lower incidence rates of catastrophic health expenditures compared to Country A for the range of thresholds shown on the horizontal axis. White bars indicate that the difference between incidence rates of catastrophic health expenditures between Country A and Country B were not statistically significant for the range of thresholds shown on the horizontal axis. For any given pairwise comparison, one can therefore observe for which thresholds Country A has higher[lower] incidence rates of catastrophic health expenditures compared to Country B, and whether such assessments are sensitive to the choice of the threshold (i.e. if the type of bars displayed changes)
