The analyses use two sets of research publications, publications from IMI projects (IMI project research) and publications from IMI-supported researchers (IMI researchers). The overall volume of IMI project research has increased rapidly since 2009 and the initiative continues to show rapid growth. This is partly to be expected as the number of funded projects rises and those projects funded earliest in the program begin to publish. To date, IMI projects have produced 657 publications, of which 629 have been matched to the Thomson Reuters Web of Science. Around three quarters of IMI project research has been published in high impact journals, i.e. those journals in the highest quartile by Journal Impact Factor. The volume of IMI research has also increased at the level of individual projects. BTCure (Call 2) is the most prolific project in any of the funding Calls with output surpassing NEWMEDS and EUROPAIN (the most prolific projects funded in Call 1) with a substantial expansion in 2013 output accompanied by rising citation impact. Among more recent projects, EU-AIMS (Call 3) has shown substantial growth in output, and its research is now cited nearly four times (3.96) world average. IMI project research is wide-ranging – the research portfolio from IMI projects covers diverse research fields. IMI project research has been published most frequently in Rheumatology, Pharmacology & Pharmacy, Neurosciences and Endocrinology & Metabolism journals. IMI project research is well-regarded. The quality of IMI project research (as indexed by citation impact) has been maintained while output has grown. The citation impact of this research is, at twice world average (2.05), internationally influential. Around one quarter of papers from IMI projects are ‛highly-cited’, that is, they belong to the world’s top ten percent of papers in that journal category and year of publication, when ranked by number of citations received. Relative to established funding organisations IMI project research performs well. Trends in the quality of this research are generally comparable to the Wellcome Trust, a leading UK funder of biomedical research. Researchers funded by IMI are well-regarded by their peers. The total research published by IMI researchers funded in Calls 1 to 5 (as opposed to that directly associated with IMI funding) is well cited with an average
