Clinical trials inform evidence-based prevention and treatment recommendations. The National Institutes of Health (NIH) and the pharmaceutical industry have been major funders of trials. In general, the pharmaceutical industry funds trials that test their own products, whereas the NIH’s funding strategies are not commercially motivated.

In 2005, registration of trials became required for publication in major journals. Registration is also required for trials that meet the definition of an “applicable clinical trial” from the US Food and Drug Administration Amendments Act 801 and that were either initiated after September 27, 2007, or initiated on or before that date and were still ongoing as of December 26, 2007. There are legal repercussions if sponsors or principal investigators do not register accurately.
