  5. You may choose to have the trials reordered by title, type of trial, status of trial, age range, trial sponsor, and protocol ID.
  6. Use the "Version" choices to display information designed for either health professionals or patients.
    • The "Health Professional" version presents more detailed information and contains technical language.
    • The "Patient" version outlines the trial's purpose, treatment plan, and some key eligibility criteria in lay language. It also has links from medical terms to definitions in the Cancer.gov dictionary.
    • Both versions provide trial contact information.
  7. Use the "Format" drop down list to choose how much information to display for each trial.
    • The Short format displays the name of each trial, which is a link to the trial's description.
    • The Medium format displays all the information in the "Short" format plus additional detailed information about the medical objectives and entry criteria for the trial.
    • The Long format displays all the information from the "Medium" format plus details about projected accrual (the expected number of participants), any results that have been published, and contact information.
    • The Custom format allows you to select which information from the "Health Professional" version to display. This format is not available for the "Patient " version.
  8. The title of each trial is a link to the trial's description.
  9. To print your search results, you must first select one or more trials to display for print. Then click on the "Display for Print" button at the bottom of the page.
