    SMQ_ALGO|Standardised MedDRA Query (SMQ) Algorithm. Boolean expression of algorithm for the SMQ. "N" if the SMQ does not utilize an algorithm.
    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. 
    SMQ_SOURCE|Standardised MedDRA Query (SMQ) Source. Source for the development of the SMQ, e.g. medical references.

    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." 
    SMQ_TERM_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.

    SMQ_TERM_SCOPE|expanded_form|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). 
    SMQ_TERM_STATUS|Standardised MedDRA Query (SMQ) Term Status. Identifies a term as active ("A") or inactive ("I") within this SMQ.
    SMQ_TERM_WEIGHT|Standardised MedDRA Query (SMQ) Term Weight. Used for some SMQ algorithms; "0" is used as default.
