The development of CDEs typically involves experts from various fields such as epidemiology, biostatistics, and clinical research. They follow a rigorous process that includes:
Literature Review: Identifying existing variables used in the field. Consultation: Engaging with stakeholders and experts to understand the essential data elements. Standardization: Defining and standardizing the variables to ensure consistency across studies. Validation: Testing the CDEs in pilot studies to ensure their reliability and validity.
