Could you join a clinical trial?
The honest picture first: most registered trials are not taking new participants, and the board below shows exactly where each one stands. Starting from your condition narrows it fastest.
And 50 more jurisdictions hold trials.
Closed covers trials terminated, suspended, withdrawn or left unverified. Every row’s four figures add to its own total; a trial with sites in several jurisdictions counts in each, so the place totals do not add to the register’s.
What has the research found?
Six findings from the peer-reviewed literature, each linked to the paper itself, so you can read what the researchers actually reported. The rest live on the research page.
