There was a weak correlation between the GDP per capita and the numbers of articles on sepsis related to the nine countries (r2 = 0.02).
Correlation analysis between GDP per capita and the total number of articles on sepsis was conducted using GraphPad Prism 5.0 software.
But we found that the correlation between the GDP per capita and the total number of articles published on sepsis was weak in the related nine countries.
Using data compiled by the National Science Foundation, the proportion of "positive" results was then regressed against a sheer measure of academic productivity: the number of articles published per-capita (i.e. per doctorate holder in academia) in each US state, controlling for the effects of per-capita research expenditure.
The growth rates of the number of articles, cumulative IF, and cumulative IF per capita for the USA did not decrease after NIH funding stagnation in 2003 [26] until 2007.
We also calculated the publication output on sepsis by normalizing the total number of articles to the gross domestic product (GDP) per capita of the included countries.
The population-adjusted research activity determined by the number of articles published, the cumulative impact factor (IF) and the cumulative IF per capita were correlated with per capita values of the GDP, health expenditure and public education expenditure.
Table 2 Number of articles, mean cumulative impact factor (IF), mean population, mean cumulative IF per capita (p.c).
When examining the distribution of articles according to each region's total population size, Latin America & Caribbean has the highest number of articles per capita, while Sub-Saharan Africa, Middle East & North Africa, and South Asia have the lowest number of articles per capita.
At the Roman Catholic reform Council of Trent (1545 63) a new foundation for the further development of canon law was expressed in the Capita de reformatione ("Articles Concerning Reform"), which were discussed and accepted in 10 of the 25 sessions.
