The Medical Advisory Secretariat (MAS) publishes the full text of its evidence-based analyses in the Ontario Health Technology Assessment Series. Links are provided under each issue listed in the series to all related publications, including Ontario Health Technology Advisory Committee recommendations and field evaluations.

When there is not enough evidence on the safety or efficacy of a particular health technology, OHTAC may request that MAS fund and oversee a field evaluation in order to provide the necessary information in an Ontario context.

The MAS publishes articles in peer-reviewed journals, presentations and other reports. View Other MAS Publications and Presentations.
