We have developed a Danish textbook in evidence-based medicine: Evidensbaseret medicin og klinisk forskningsmetode. Supplementary online chapters are available here, e.g. see the chapter on critically appraised topics (CAT).
The Cochrane Interactive Learning modules offer a useful introduction to systematic reviews and are freely available for OUH employees and SDU employees and students. To get access SDU employees can use their health.sdu.dk email address and follow this guide. OUH employees and SDU students must use the internet at their work/at the University when registering for the first time and follow this guide.
See the Cochrane Training website for other learning resources and further information about workshops and courses. The Cochrane Handbook for Systematic Reviews of Interventions and the JBI Manual for Evidence Synthesis are also valuable resources and freely available online. Cochrane is also developing an updated Handbook for Systematic Reviews of Diagnostic Test Accuracy. See also this a useful calculator for diagnostic tests (developed by Mathias Weis Damkjær).
