Attribute Counts

Attribute TypeExpanded FormCount
SMQ_TERM_CATStandardised 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."181194
SMQ_TERM_LMVERSIONStandardised MedDRA Query (SMQ) Last Modified Version. Version of MedDRA in which term was last modified in the SMQ.181194
SMQ_TERM_STATUSStandardised MedDRA Query (SMQ) Term Status. Identifies a term as active ("A") or inactive ("I") within this SMQ.181194
SMQ_TERM_ADDVERSIONStandardised MedDRA Query (SMQ) Addition Version. Version of MedDRA in which term was added to the SMQ.181194
SMQ_TERM_WEIGHTStandardised MedDRA Query (SMQ) Term Weight. Used for some SMQ algorithms; "0" is used as default.181194
SMQ_TERM_SCOPEStandardised 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).181194
SMQ_TERM_LEVELStandardised MedDRA Query (SMQ) Term Level. The MedDRA hierarchy level of a term (4=PT, 5=LLT) or 0 (zero) for a child SMQ.54479
MPSMedDRA primary SOC (PTs may have multiple treepositions, but each has a primary soc)25077
SMQ_LEVELStandardised 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.229
SMQ_ALGOStandardised MedDRA Query (SMQ) Algorithm. Boolean expression of algorithm for the SMQ. "N" if the SMQ does not utilize an algorithm.229
SMQ_STATUSStandardised MedDRA Query (SMQ) Status. "A" = active; "I" = inactive.229
SMQ_SOURCEStandardised MedDRA Query (SMQ) Source. Source for the development of the SMQ, e.g. medical references.189
SOSScope Statement96
