Figure 21.

Box and whisker charts plotting Global Burden of Disease super-region against the proportion of the population in need that receives effective cataract surgery. The highest median coverage is found in high-income countries and the lowest in sub-Saharan Africa. Women have lower median effective cataract surgical coverage rates in all regions except Latin America and the Caribbean.

Effective cataract surgical coverage by Global Burden of Disease super region

(A) Cluster-adjusted, age-adjusted, and sex-adjusted estimates. (B) Cluster-adjusted, age-adjusted, and sex-disaggregated estimates. Box and whisker plots; midlines are the median, boxes represent IQR, whiskers are upper and lower adjacent values. Outliers are plotted as individual dots. Countries within regions are represented by the most recent national or subnational Rapid Assessment of Avoidable Blindness survey and if two or more assessments occurred within 2 years, the median of estimates was used (appendix 1 pp 84–85).
