SDTM, or Study Data Tabulation Model, is a standard format used in clinical research to organize and submit data. It provides a consistent structure for clinical trial data, making it easier for regulatory agencies, like the FDA, to review and analyze the information. The SDTM framework includes specific domains for different types of data, such as demographics, adverse events, and laboratory results. By adhering to this standardized format, researchers can ensure that their data is clear and accessible, facilitating better communication and understanding among stakeholders in the clinical research process.
