Abstract
The European & Developing Countries Clinical Trials Partnership (EDCTP) is a partnership of European and sub-Saharan African countries that aims to accelerate the development of medical interventions against poverty-related diseases (PRDs). A bibliometric analysis was conducted to 1) measure research output from European and African researchers on PRDs, 2) describe collaboration patterns, and 3) assess the citation impact of clinical research funded by EDCTP.
Disease-specific research publications were identified in Thomson Reuters Web of Science using search terms in titles, abstracts and keywords. Publication data, including citation counts, were extracted for 2003–2011. Analyses including output, share of global papers, normalised citation impact (NCI), and geographical distribution are presented. Data are presented as five-year moving averages. European EDCTP member countries accounted for ~33% of global research output in PRDs and sub-Saharan African countries for ~10% (2007–2011). Both regions contributed more to the global research output in malaria (43.4% and 22.2%, respectively). The overall number of PRD papers from sub-Saharan Africa increased markedly (>47%) since 2003, particularly for HIV/AIDS (102%) and tuberculosis (TB) (81%), and principally involving Southern and East Africa. For 2007–2011, European and sub-Saharan African research collaboration on PRDs was highly cited compared with the world average (NCI in brackets): HIV/AIDS 1.62 (NCI: 1.16), TB 2.11 (NCI: 1.06), malaria 1.81 (NCI: 1.22), and neglected infectious diseases 1.34 (NCI: 0.97). The NCI of EDCTP-funded papers for 2003–2011 was exceptionally high for HIV/AIDS (3.24), TB (4.08) and HIV/TB co-infection (5.10) compared with global research benchmarks (1.14, 1.05 and 1.35, respectively).
The volume and citation impact of papers from sub-Saharan Africa has increased since 2003, as has collaborative research between Europe and sub-Saharan Africa. >90% of publications from EDCTP-funded research were published in high-impact journals and are highly cited. These findings corroborate the benefit of collaborative research on PRDs.

These findings corroborate the benefit of collaborative research on PRDs.</p></sec></abstract><abstract abstract-type="summary"><title>Author Summary</title><p>The European & Developing Countries Clinical Trials Partnership (EDCTP) was created in 2003 as a European response to the global health crisis caused by the three main poverty-related diseases (PRDs) of HIV/AIDS, tuberculosis and malaria. EDCTP funds research focusing on clinical trials for diagnosing, preventing and treating these diseases. We conducted a bibliometric analysis to 1) measure research output and citation impact from European and African researchers working on PRDs, 2) describe collaboration patterns, and 3) assess the citation impact of research funded by EDCTP. Citation analysis is a commonly used bibliometric tool to analyse scientific literature. Overall, the volume and citation impact of papers from sub-Saharan Africa has increased since 2003, as has collaborative research between Europe and sub-Saharan Africa. Papers arising from collaborative research had a higher citation impact than non-collaborative research and >90% of publications from EDCTP-funded research projects were published in high-impact journals. These results suggest that research on PRDs in sub-Saharan Africa is growing and that the EDCTP partnership contributes to high-impact, collaborative research published in high-impact journals. By providing research funds and supporting activities to strengthen the research environment, the partnership contributes to sub-Saharan African researchers taking the lead in PRD research.</p></abstract><funding-group><funding-statement>This project was funded by a grant received under the European Commission Framework Programme 7, (call: FP7-Adhoc-2007-13, grant agreement no: 304786).
