Abstract

In the clinical development of diagnostic procedures, studies are performed to measure the efficacy of the new method in the target population. Those new methods could be new laboratory tests, which measure some tumor marker to evaluate the disease status of a patient. Other examples are imaging methods like ultrasound, where several raters are asked to assess the images.
