VariableName VariableLabel Type Role Note Core
STUDYID Study Identifier Char Identifier Unique identifier for a study. Req
DOMAIN Domain Abbreviation Char Identifier Two-character abbreviation for the domain. Req
USUBJID Unique Subject Identifier Char Identifier Identifier used to uniquely identify a subject across all studies for all applications or submissions involving the product. Req
CESEQ Sequence Number Num Identifier Sequence Number given to ensure uniqueness of subject records within a domain. May be any valid number. Req
CEGRPID Group ID Char Identifier Used to tie together a block of related records for a subject within a domain. Perm
CEREFID Reference ID Char Identifier Internal or external identifier. Perm
CESPID Sponsor-Defined Identifier Char Identifier Sponsor-defined reference number. Perhaps pre-printed on the CRF as an explicit line identifier or defined in the sponsor’s operational database. Example: Line number on a CRF page. Perm
CETERM Reported Term for the Clinical Event Char Topic Term for the medical condition or event. Most likely pre-printed on CRF. Req
CEDECOD Dictionary-Derived Term Char Synonym Qualifier Controlled terminology for the name of the clinical event. The sponsor is expected to provide the dictionary name and version used to map the terms utilizing the define.xml external codelist attributes Perm
CECAT Category for Clinical Event Char Grouping Qualifier Used to define a category of related records. Perm
CESCAT Subcategory for Clinical Event Char Grouping Qualifier A further categorization of the condition or event. Perm
CEPRESP Clinical Event Pre-Specified Char Variable Qualifier Used to indicate whether the Event in CETERM was pre-specified. Value is Y for pre-specified events, null for spontaneously reported events. Perm
CEOCCUR Clinical Event Occurrence Char Record Qualifier Used when the occurrence of specific events is solicited to indicate whether or not a clinical event occurred. Values are null for spontaneously reported events. Perm
CESTAT Completion Status Char Record Qualifier The status indicates that a question from a pre-specified list was not answered. Perm
CEREASND Reason Clinical Event Not Collected Char Record Qualifier Describes the reason clinical event data was not collected. Used in conjunction with CESTAT when value is NOT DONE. Perm
CEBODSYS Body System or Organ Class Char Record Qualifier Dictionary-derived. Body system or organ class that is involved in an event or measurement from a standard hierarchy (e.g., MedDRA). When using a multi-axial dictionary such as MedDRA, this should contain the SOC used for the sponsor’s analyses and summary tables which may not necessarily be the primary SOC. Perm
CESEV Severity/Intensity Char Record Qualifier The severity or intensity of the event. Examples: MILD, MODERATE, SEVERE Perm
CEDTC Date/Time of Event Collection Char Timing Perm
CESTDTC Start Date/Time of Clinical Event Char Timing Perm
CEENDTC End Date/Time of Clinical Event Char Timing Perm
CEDY Study Day of Event Collection Num Timing 1. Study day of clinical event collection, measured as integer days. 2. Algorithm for calculations must be relative to the sponsor-defined RFSTDTC variable in Demographics. This formula should be consistent across the submission. Perm
CESTRF Start Relative to Reference Period Char Timing Describes the start of the clinical event relative to the sponsor-defined referenceperiod. The sponsor-defined reference period is a continuous period of time defined by a discrete starting point and a discrete ending point (represented by RFSTDTC and RFENDTC in Demographics). Perm
CEENRF End Relative to Reference Period Char Timing Describes the end of the event relative to the sponsor-defined reference period. The sponsor-defined reference period is a continuous period of time defined by adiscrete starting point and a discrete ending point (represented by RFSTDTC and RFENDTC in Demographics). Perm
CESTRTPT Start Relative to Reference Time Point Char Timing Identifies the start of the observation as being before or after the reference time point defined by variable CESTTPT. Perm
CESTTPT Start Reference Time Point Char Timing Description or date/time in ISO 8601 character format of the sponsor-defined reference point referred to by --STRTPT. Examples: "2003-12-15" or "VISIT 1". Perm
CEENRTPT End Relative to Reference Time Point Char Timing Identifies the end of the event as being before or after the reference time point defined by variable CEENTPT. Perm
CEENTPT End Reference Time Point Char Timing Description or date/time in ISO 8601 character format of the reference point referred to by CEENRTPT. Examples: "2003-12-25" or "VISIT 2". Perm
