Detailed Explanation
The case report form represents the primary tool for capturing clinical trial data in a structured, standardized format that facilitates analysis and regulatory review. Each CRF is specifically designed to collect the information required by the protocol, translating the study's scientific objectives into concrete data collection instruments. Whether in paper format or, increasingly common today, as electronic case report forms, these documents must enable accurate, complete, and legible recording of all protocol-specified data in a manner that supports verification against source documents.
