Biostatistics and Study Design Work Group

Pragmatic clinical trials require particular design considerations, including input from stakeholders, heterogeneity of patient populations to enhance generalizability, treatments that are readily applied in the clinical setting, and evaluation of clinically impactful outcomes. Sensitivity to biases in recruitment techniques, sampling approaches, and randomization methods is important in pragmatic studies of non-pharmacological approaches to pain management. The Biostatistics and Study Design Work Group focuses on the efficient conduct of pragmatic clinical trials by developing methodological standards for their design and implementation.
