There are three specific categories of grey literature that we search: Regulatory Information, Trial Registries, Abstracts and Conferences. On the tracking worksheet there is a list all the sources the SRC routinely searches (bulleted titles) for its own reports, others listed serve as reminders that they are available if further research is needed or if somebody asks for suggestions of additional places to locate grey literature.

The Canadian Agency for Drugs and Technologies in Health (CADTH) is a national body that provides Canada’s federal, provincial and territorial health care decision makers with credible, impartial advice and evidence-based information about the effectiveness and efficiency of drugs and other health technologies.
