title: An ongoing randomized clinical trial in dysphagia.
abstract: Most of us who have clinical practices firmly contend that the treatments we provide cause beneficial changes in the lives of our patients. Indeed, our clinical experience engenders strong convictions to the point of believing that withholding treatment creates ethical violations. Intellectually, however, we must recognize that the value of treatment needs to be validated through scientific evidence. This paper examines the use of randomized clinical trials as a means of obtaining the type of evidence relevant for work in health care settings.
