| SMQ_TERM_CAT | Standardised MedDRA Query (SMQ) Term Category. A single alphabetical letter indicating the category of the term for application of the SMQ algorithm. If the SMQ does not use algorithms, then all Term_category values are assigned "A." For a child SMQ, this field is assigned "S." | 161634 |
| SMQ_TERM_LMVERSION | Standardised MedDRA Query (SMQ) Last Modified Version. Version of MedDRA in which term was last modified in the SMQ. | 161634 |
| SMQ_TERM_STATUS | Standardised MedDRA Query (SMQ) Term Status. Identifies a term as active ("A") or inactive ("I") within this SMQ. | 161634 |
| SMQ_TERM_ADDVERSION | Standardised MedDRA Query (SMQ) Addition Version. Version of MedDRA in which term was added to the SMQ. | 161634 |
| SMQ_TERM_SCOPE | Standardised MedDRA Query (SMQ) Term Scope. Defines the MedDRA term as a member of the broad scope (1), narrow scope (2) of the SMQ search, or a child SMQ (0) (zero). | 161634 |
| SMQ_TERM_WEIGHT | Standardised MedDRA Query (SMQ) Term Weight. Used for some SMQ algorithms; "0" is used as default. | 161634 |
| SMQ_TERM_LEVEL | Standardised MedDRA Query (SMQ) Term Level. The MedDRA hierarchy level of a term (4=PT, 5=LLT) or 0 (zero) for a child SMQ. | 49736 |
| MPS | MedDRA primary SOC (PTs may have multiple treepositions, but each has a primary soc) | 23954 |
| SMQ_LEVEL | Standardised MedDRA Query (SMQ) Level. Value between 1 and 5 identifying the level of the SMQ within the hierarchy of SMQs; 1 is the most general, 5 is the most narrow. | 225 |
| SMQ_ALGO | Standardised MedDRA Query (SMQ) Algorithm. Boolean expression of algorithm for the SMQ. "N" if the SMQ does not utilize an algorithm. | 225 |
| SMQ_STATUS | Standardised MedDRA Query (SMQ) Status. "A" = active; "I" = inactive. | 225 |
| SMQ_SOURCE | Standardised MedDRA Query (SMQ) Source. Source for the development of the SMQ, e.g. medical references. | 185 |
| SOS | Scope Statement | 132 |
| MISO | MedDRA Serial Code International SOC Sort Order Digit (01-26) | 27 |
