Hospitalizations: The number of hospitalizations annually for a specific disease. Incidence: The number of new cases annually of a specific disease.

Mortality: The number of deaths resulting annually from a specific disease listed as the underlying or primary cause.

Prescriptions: The number of prescriptions written annually for medications to treat a specific disease.

Clinical Trials

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and other components of the National Institutes of Health (NIH) conduct and support research into many diseases and conditions.

What are clinical trials, and are they right for you?

Clinical trials are part of clinical research and at the heart of all medical advances. Clinical trials look at new ways to prevent, detect, or treat disease. Researchers also use clinical trials to look at other aspects of care, such as improving the quality of life for people with chronic illnesses. Find out if clinical trials are right for you.

What clinical trials are open?

Clinical trials that are currently open and are recruiting can be viewed at ClinicalTrials.gov.

This information may contain content about medications and, when taken as prescribed, the conditions they treat. When prepared, this content included the most current information available.
