The Transfusion Evidence Library is an online information resource that provides access to evidence-based publications (Systematic Reviews, Randomised Controlled Trials and Health Economic Evaluations) on all aspects of transfusion medicine, and expert Clinical Commentaries on selected studies. Articles are pre-selected for clinical relevance and methodological quality, to easily identify high quality papers and to keep up-to-date in your field. It is produced by the NHS Blood and Transplant Systematic Review Initiative and funded by the four UK Blood Services and Oxford Biomedical Research Centre. Transfusion Evidence Library is available free of charge in the UK.
