OBJECTIVES: To review study design issues related to clinical trials led by oncology nurses, with special attention to those conducted within the cooperative group setting; to emphasize the importance of the statistician's role in the process of clinical trials. DATA SOURCES: Studies available at clinicaltrials.gov using experimental designs that have been published in peer-reviewed journals; cooperative group trials are highlighted. CONCLUSION: The clinical trial is a primary means to test intervention efficacy. A properly designed and powered study with clear and measurable objectives is as important as the intervention itself. IMPLICATIONS FOR NURSING PRACTICE: Collaboration among the study team, including the statistician, is central in developing and conducting appropriately designed studies. For optimal results, collaboration is an ongoing process that should begin early on.
