WHO data on annual health research expenditures were derived from an article by Terry et al. [55]. The Global Fund and UNAIDS data were acquired through personal communications. For the other organizations, no data were available or could be provided. For these organizations, annual health research expenditures were approximated by extracting expenditure figures from G-FINDER, which is limited to health research focused on product development (not available for UNITAID) [54]. It should be noted that some of these organizations, such as the World Bank, conduct a substantial amount of health policy research every year. Since G-FINDER’s data were the only data available on World Bank expenditures on health research, policy research expenditures have not been included
