The SUPPEM dataset is used to represent the NSVs used for coding the malfunction or event. The parent domain (RDOMAIN) is EM, and IDVAR is EMSEQ. QNAM holds the name of the supplemental qualifier variable being defined. This only shows the data for subject 2029. The data recorded in QVAL applies to the subject’s records, where IDVAR (EMSEQ) equals the value specified in IDVARVAL.
