These stories, the product of an 18-month investigation of the Bill & Melinda Gates Foundation, are based in part on a review of hundreds of foundation grant descriptions, policies, evaluation reports and tax returns. Reporting included interviews with foundation and investment experts; patients, medical professionals and administrators in Lesotho, Rwanda, Nigeria, South Africa and other African nations; and global health experts in Europe, Africa and the United States.

Hundreds of scholarly articles, books and studies on philanthropy and health conditions in Africa were reviewed, along with thousands of pages of financial and performance data, reports and evaluations from the Global Fund to Fight AIDS, Tuberculosis and Malaria, the GAVI Alliance and other financing groups and aid organizations. Statistical data on health conditions in Africa were obtained from the World Health Organization, the World Bank and UNICEF, as well as national ministries of health and nongovernmental organizations.
