Figure. From: Cost effectiveness of strategies to combat vision and hearing loss in sub-Saharan Africa and South East Asia: mathematical modelling study.

Incremental cost effectiveness ratios and cumulative cost per capita ($Int) of interventions to combat vision and hearing loss in WHO sub-Saharan African sub-region AfrE. Cost per DALY averted (bars) ranges from very cost effective (such as treatment of chronic otitis media with topical antibiotics at 50% coverage (COM-2) costing $Int16 per DALY averted) to least cost effective (annual screening of schoolchildren and screening of adults every five years for hearing loss (HEA-35) costing $Int3639 per DALY averted). Cumulative cost per capita (dashed line) shows cost if interventions are implemented in order of decreasing economic attractiveness. In case only COM-2 is implemented, cost per capita is $Int0.01. If all shown interventions are implemented, costs per capita increase to $Int14.86. See table 4 for descriptions of the intervention codes
