Center for Evidenced Based Medicine

The Centre for Evidence-based Medicine was established in Oxford as the first of several UK centers with the aim of promoting evidence-based health care. The CEBM provides free support and resources to doctors, clinicians, teachers and others interested in learning more about EBM.

EBM Tools section has a great deal of information

The critical appraisal section is quite good and has documents to help you review articles and understand terminology better.  http://www.cebm.net/index.aspx?o=1157
