common data elements

Common Data Elements (CDEs) are standardized pieces of information used across studies, organizations, or systems to ensure consistency and clarity. They define specific data points, like age, gender, or test results, in a uniform way. By using CDEs, researchers and researchers can compare and combine data accurately, reducing confusion and errors. Think of them as a shared language for data that helps teams work together more effectively and ensures that everyone interprets information the same way. This standardization improves data quality, supports reliable analysis, and accelerates research and decision-making.
