Between 2003 and 2007, Thomson Reuters indexed 81,289 papers that listed at
least one author address in Sweden. Of those papers, the highest percentage
appeared in journals classified under the heading of immunology. As the
right-hand column indicates, the citations-per-paper (impact) mark for
Swedish immunology papers was 16% below the 2003-07 world average for the
field (9.09 cites per paper for Sweden, versus a world mark of 10.78 cites
per paper). On the other hand, Sweden-based researchers surpassed the world
average in all the other fields save for psychology/psychiatry, with
notably strong performance in agricultural sciences (56% above the world
average), ecology/environment (44% above), plant & animal sciences
(+41%), space science (+36%), and physics (+34%).
