Background: Patient preferences can affect colorectal cancer (CRC) screening test use. We compared utility-based preferences for alternative CRC screening tests from a stated-preference discrete-choice survey of the general population and physicians in Canada and the United States. <P>Methods:...</p>

The development of mutations associated with resistance to antiretroviral therapy (ART) has been shown to be a major cause of treatment failure in patients infected with HIV-1. These resistance mutations can be assessed by a genotyping test that probes for specific mutations within the HIV...

The transfer study, a technique used in cost-benefit analysis, is an increasingly important tool used by government agencies to assess environmental regulatory policy. This innovative book develops protocols for using the transfer method to approach environmental problems and introduces several...
