title: Selecting control interventions for clinical outcome studies.
abstract: In the current research environment the design and management of control groups is becoming more complex. The selection of a control group design is dependent on study goals, presence and quality of existing interventions, urgency of the problem or issue being addressed by the intervention, and factors related to the study site. The purpose of the presentation is to identify various approaches to the design of control groups in experimental studies and to identify their strengths, limitations, and applications. A case study exemplifies the issues associated with control group selection and design.
