| ECSCAT | Subcategory of Treatment | Char | * | Grouping Qualifier | A further categorization of ECCAT values. | Perm |
| ECPRESP | Pre-Specified | Char | (NY) | Variable Qualifier | Used when a specific intervention is pre-specified. Values should be "Y" or null. | Perm |
| ECOCCUR | Occurrence | Char | (NY) | Record Qualifier | Used to indicate whether a treatment occurred when information about the occurrence is solicited. ECOCCUR = "N" when a treatment was not taken, not given, or missed. | Perm |
| ECDOSE | Dose | Num | Record Qualifier | Amount of ECTRT when numeric. Not populated when ECDOSTXT is populated. | Exp | |
| ECDOSTXT | Dose Description | Char | Record Qualifier | Amount of ECTRT when non-numeric. Dosing amounts or a range of dosing information collected in text form. Example: "200-400". Not populated when ECDOSE is populated. | Perm | |
| ECDOSU | Dose Units | Char | (UNIT) | Variable Qualifier | Units for ECDOSE, ECDOSTOT, or ECDOSTXT. | Exp |
| ECDOSFRM | Dose Form | Char | (FRM) | Variable Qualifier | Dose form for ECTRT. Examples: "TABLET", "LOTION". | Exp |
| ECDOSFRQ | Dosing Frequency per Interval | Char | (FREQ) | Variable Qualifier | Usually expressed as the number of repeated administrations of ECDOSE within a specific time period. Examples: "Q2H", "QD", "BID". | Perm |
| ECDOSTOT | Total Daily Dose | Num | Record Qualifier | Total daily dose of ECTRT using the units in ECDOSU. Used when dosing is collected as Total Daily Dose. | Perm | |
| ECDOSRGM | Intended Dose Regimen | Char | Variable Qualifier | Text description of the intended schedule or regimen for the Intervention. Example: "TWO WEEKS ON", "TWO WEEKS OFF". | Perm | |
| ECROUTE | Route of Administration | Char | (ROUTE) | Variable Qualifier | Route of administration for the intervention. Examples: "ORAL", "INTRAVENOUS". | Perm |
| ECLOT | Lot Number | Char | Record Qualifier | Lot Number of the ECTRT product. | Perm | |
| ECLOC | Location of Dose Administration | Char | (LOC) | Record Qualifier | Specifies location of administration. Example: "ARM", "LIP". | Perm |
| ECLAT | Laterality | Char | (LAT) | Variable Qualifier | Qualifier for anatomical location further detailing laterality of the intervention administration. Examples: "LEFT", "RIGHT". | Perm |
| ECDIR | Directionality | Char | (DIR) | Variable Qualifier | Qualifier for anatomical location further detailing directionality. Examples: "ANTERIOR", "LOWER", "PROXIMAL", "UPPER". | Perm |
| ECPORTOT | Portion or Totality | Char | (PORTOT) | Variable Qualifier | Qualifier for anatomical location further detailing distribution, which means arrangement of, apportioning of. Examples: "ENTIRE", "SINGLE", "SEGMENT". | Perm |
| ECFAST | Fasting Status | Char | (NY) | Record Qualifier | Indicator used to identify fasting status. Examples: "Y", "N". | Perm |
| ECPSTRG | Pharmaceutical Strength | Num | Record Qualifier | Amount of an active ingredient expressed quantitatively per dosage unit, per unit of volume, or per unit of weight, according to the pharmaceutical dose form. | Perm | |
| ECPSTRGU | Pharmaceutical Strength Units | Char | * | Variable Qualifier | Unit for ECPSTRG. Examples: "mg/TABLET", "mg/mL". | Perm |
| ECADJ | Reason for Dose Adjustment | Char | Record Qualifier | Describes reason or explanation of why a dose is adjusted. | Perm | |
| TAETORD | Planned Order of Element within Arm | Num | Timing | Number that gives the planned order of the Element within the Arm. | Perm | |
| EPOCH | Epoch | Char | (EPOCH) | Timing | Trial Epoch of the exposure as collected record. Examples: "RUN-IN", "TREATMENT". | Perm |

| ECENDTC | End Date/Time of Treatment | Char | ISO 8601 | Timing | The date/time when administration of the treatment indicated by ECTRT and ECDOSE ended. For administrations considered given at a point in time (e.g., oral tablet, pre-filled syringe injection), where only an administration date/time is collected, ECSTDTC should be copied to ECENDTC as the standard representation. | Exp |
