The content lists NCI codes and CDISC submission values for key concepts such as DATEFL, TIMEFL, and derivation-related fields like DTYPE. Definitions describe how date and time imputation levels are represented and how derivation techniques (e.g., interpolation, LOCF, baseline carried forward) guide analysis value generation, including whether codelists are
