Research Insights
What the Published HBOT Literature Shows
Original analyses of our database of 14,529 indexed hyperbaric oxygen therapy studies: how the research has grown, what kinds of studies exist, how much is Canadian-led, and where it concentrates. These pages describe the research landscape only.
Read these as research volume, not effectiveness. A larger number of published studies means a topic has been studied more often. It does not mean hyperbaric oxygen therapy is more effective for that condition, or that it is appropriate for any individual. For which conditions are recognised in Canada, see the conditions pages.
