Clinical Trials

“Clinical Trials” here are the medical studies for humans, and refer to the intervention trials on prevention, diagnosis, or treatment. Although intervention using medical supplies or medical equipment is at the core, intervention of meals, exercises, and rehabilitation could also be included. For example, the randomized controlled trial using medicine can be included in "Clinical Trials". The prospective observational study without intervention should be applied to “Cohort Studies”.

Cohort Studies

“Cohort Studies” here refer to prospective epidemiological studies. These include prospective observational studies based on registry. * We only accept those “Clinical Trials / Cohort Studies” that will be announced for the first time at the JCS2021.
