a. Refers to the age group to whom the intervention is targeted and not necessarily the one that is benefiting.

b. Ranges in cost-effectiveness reflect the variation in point estimates for specific interventions included in each intervention cluster and do not represent either variation across regions or statistical confidence intervals. Point estimates were obtained directly from the relevant chapters, calculated as the midpoint of range estimates reported in the chapters, or calculated from a population-weighted average of the region-specific estimates reported in the chapters. DALYs and deaths potentially avertable are for a 20 percentage point increase in intervention coverage in a hypothetical sample population of 1 million.

c. See table 2.1.

d. Cost-effectiveness ratio calculated from deaths averted only.
