Benefit-cost ratios of eye health investment in low- and middle-income countries
CI: confidence interval.
Notes: Benefit-cost ratios derived from individual studies identified via systematic review are labelled with the relevant study. The other four benefit-cost ratios are from the economic modelling approach from scaling interventions in India. CIs in economic modelling analysis are based on Monte Carlo simulations, varying key parameters simultaneously. CIs from individual studies based on reported variation in impact parameters. Results assume a 3% discount rate.
