Almost 25% of the world's scientists live in developing countries. However, these scientists publish less than 3% of the world's papers. The top 7 cited countries are those with the 7 largest economies. While, for instance and as a surprising point the Iranian Federation of Public Health Schools has 18 schools in the country, of which two are epidemiology training centers. Iran publishes 76 medical journals, of which six are in English, but none is recognized by the world’s major indexing and citation organizations.
