Publications and cumulative impact factors in urological journals by authors from European Union countries during 2000–2005. Values correspond to the total number for each country during this period: , number of publications; , cumulative impact factor. Each publication was counted once for every country in which the institution of the author was located. The cumulative impact factor of a country was calculated by multiplying the number of publications in a certain journal with the journal impact factor, for each year studied, and then summing up these data from all selected journals.

Publication activity of the European Union countries in urological journals during 2000–2005 shown as function of the national socio-economic factors. The publication activity, measured as the ratio of the cumulative impact factors to million of inhabitants is shown as function of the (A) gross domestic product, (B) gross domestic expenditure on research and experimental development and (C) health care expenditure, in each case per person.
