Interventional clinical trials registered per million population per country worldwide
Since 1999, there has been worldwide growth in interventional clinical trial registrations, especially amongst top-contributing countries. The global average stands at approximately 97 registered trials per million people from 2009 to 2022, highlighting the need for continued efforts to improve trial registration and production. Smaller Western countries lead in interventional clinical trials per million population.
