Popis: | A clinical trial of the efficacy of a contrast agent used with a diagnostic procedure may present design and analysis issues that need to be considered and managed. Choice of primary variable and summary measures, multiple evaluations on each patient for the primary efficacy analysis (multiplicity), and uninterpretable or nonassessable images or regions of interest in images are three specific concerns discussed. Several methods are presented that should be considered for handling some of these issues. |
