SDTMIG v3.4 Metadata Check for Domain Specification Table 1.4.1
Metadata check macro is applied and detected no issues. This notice is provided as a visual reminder. It will be removed during final publication. Release Notes
| Variable Name | Variable Label | Type | Controlled Terms, Codelist or Format1 | Role | CDISC Notes | Core |
|---|---|---|---|---|---|---|
| STUDYID | Study Identifier | Char | Identifier | Unique identifier for a study. | Req | |
| DOMAIN | Domain Abbreviation | Char | DM | 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. This must be a unique value, and could be a compound identifier formed by concatenating STUDYID-SITEID-SUBJID. | Req | |
| SUBJID | Subject Identifier for the Study | Char | Topic | Subject identifier, which must be unique within the study. Often the ID of the subject as recorded on a CRF. | Req | |
| RFSTDTC | Subject Reference Start Date/Time | Char | ISO 8601 datetime or interval | Record Qualifier | Reference start date/time for the subject in ISO 8601 character format. Usually equivalent to date/time when subject was first exposed to study treatment. See assumption 9 for additional detail on when RFSTDTC may be null. | Exp |
| RFENDTC | Subject Reference End Date/Time | Char | ISO 8601 datetime or interval | Record Qualifier | Reference end date/time for the subject in ISO 8601 character format. Usually equivalent to the date/time when subject was determined to have ended the trial, and often equivalent to date/time of last exposure to study treatment. Required for all randomized subjects; null for screen failures or unassigned subjects. | Exp |
| RFXSTDTC | Date/Time of First Study Treatment | Char | ISO 8601 datetime or interval | Record Qualifier | First date/time of exposure to any protocol-specified treatment or therapy, equal to the earliest value of EXSTDTC. | Exp |
| RFXENDTC | Date/Time of Last Study Treatment | Char | ISO 8601 datetime or interval | Record Qualifier | Last date/time of exposure to any protocol-specified treatment or therapy, equal to the latest value of EXENDTC (or the latest value of EXSTDTC if EXENDTC was not collected or is missing). | Exp |
| RFICDTC | Date/Time of Informed Consent | Char | ISO 8601 datetime or interval | Record Qualifier | Date/time of informed consent in ISO 8601 character format. This will be the same as the date of informed consent in the Disposition domain, if that protocol milestone is documented. Would be null only in studies not collecting the date of informed consent. | Exp |
| RFPENDTC | Date/Time of End of Participation | Char | ISO 8601 datetime or interval | Record Qualifier | Date/time when subject ended participation or follow-up in a trial, as defined in the protocol, in ISO 8601 character format. Should correspond to the last known date of contact. Examples include completion date, withdrawal date, last follow-up, date recorded for lost to follow up, and death date. | Exp |
| DTHDTC | Date/Time of Death | Char | ISO 8601 datetime or interval | Record Qualifier | Date/time of death for any subject who died, in ISO 8601 format. Should represent the date/time that is captured in the clinical-trial database. | Exp |
| DTHFL | Subject Death Flag | Char | (NY) | Record Qualifier | Indicates the subject died. Should be "Y" or null. Should be populated even when the death date is unknown. | Exp |
| SITEID | Study Site Identifier | Char | * | Record Qualifier | Unique identifier for a site within a study. | Req |
| INVID | Investigator Identifier | Char | Record Qualifier | An identifier to describe the Investigator for the study. May be used in addition to SITEID. Not needed if SITEID is equivalent to INVID. | Perm | |
| INVNAM | Investigator Name | Char | Synonym Qualifier | Name of the investigator for a site. | Perm | |
| BRTHDTC | Date/Time of Birth | Char | ISO 8601 datetime or interval | Record Qualifier | Date/time of birth of the subject. | Perm |
| AGE | Age | Num | Record Qualifier | Age expressed in AGEU. May be derived from RFSTDTC and BRTHDTC, but BRTHDTC may not be available in all cases (due to subject privacy concerns). | Exp | |
| AGEU | Age Units | Char | (AGEU) | Variable Qualifier | Units associated with AGE. | Exp |
| SEX | Sex | Char | (SEX) | Record Qualifier | Sex of the subject. | Req |
| RACE | Race | Char | (RACE) | Record Qualifier | Race of the subject. Sponsors should refer to the FDA guidance2 regarding the collection of race. See assumption below regarding RACE. | Exp |
| ETHNIC | Ethnicity | Char | (ETHNIC) | Record Qualifier | The ethnicity of the subject. Sponsors should refer to the FDA guidance1 regarding the collection of ethnicity. | Perm |
| ARMCD | Planned Arm Code | Char | * | Record Qualifier | ARMCD is limited to 20 characters. It is not subject to the character restrictions that apply to TESTCD. The maximum length of ARMCD is longer than for other "short" variables to accommodate the kind of values that are likely to be needed for crossover trials. For example, if ARMCD values for a 7-period crossover were constructed using 2-character abbreviations for each treatment and separating hyphens, the length of ARMCD values would be 20. If the subject was not assigned to a trial arm, ARMCD is null and ARMNRS is populated. With the exception of studies which use multistage arm assignments, must be a value of ARMCD in the Trial Arms dataset. | Exp |
| ARM | Description of Planned Arm | Char | * | Synonym Qualifier | Name of the arm to which the subject was assigned. If the subject was not assigned to an arm, ARM is null and ARMNRS is populated. With the exception of studies which use multistage arm assignments, must be a value of ARM in the Trial Arms dataset. | Exp |
| ACTARMCD | Actual Arm Code | Char | * | Record Qualifier | Code of actual arm. ACTARMCD is limited to 20 characters. It is not subject to the character restrictions that apply to TESTCD. The maximum length of ACTARMCD is longer than for other short variables to accommodate the kind of values that are likely to be needed for crossover trials. With the exception of studies which use multistage arm assignments, must be a value of ARMCD in the Trial Arms dataset. If the subject was not assigned to an arm or followed a course not described by any planned arm, ACTARMCD is null and ARMNRS is populated. | Exp |
| ACTARM | Description of Actual Arm | Char | * | Synonym Qualifier | Description of actual arm. With the exception of studies which use multistage arm assignments, must be a value of ARM in the Trial Arms dataset. If the subject was not assigned to an arm or followed a course not described by any planned arm, ACTARM is null and ARMNRS is populated. | Exp |
| ARMNRS | Reason Arm and/or Actual Arm is Null | Char | (ARMNULRS) | Record Qualifier | A coded reason that arm variables (ARM and ARMCD) and/or actual arm variables (ACTARM and ACTARMCD) are null. Examples: "SCREEN FAILURE", "NOT ASSIGNED", "ASSIGNED, NOT TREATED", "UNPLANNED TREATMENT". It is assumed that if the arm and actual arm variables are null, the same reason applies to both arm and actual arm. | Exp |
| ACTARMUD | Description of Unplanned Actual Arm | Char | Record Qualifier | A description of actual treatment for a subject who did not receive treatment described in a planned trial arm. | Exp | |
| COUNTRY | Country | Char | Record Qualifier | Country of the investigational site in which the subject participated in the trial. Generally represented using ISO 3166-1 Alpha-3. Note that regulatory agency specific requirements (e.g., US FDA) may require other terminologies; in such cases, follow regulatory requirements. | Req | |
| DMDTC | Date/Time of Collection | Char | ISO 8601 datetime or interval | Timing | Date/time of demographic data collection. | Perm |
| DMDY | Study Day of Collection | Num | Timing | Study day of collection measured as integer days. | Perm |
