The associated SDTM datasets for the data collected above are provided below. An abbreviated Tobacco Product Identifiers and Descriptors (TO) domain example is provided for reference below. TOBA-121 - Getting issue details... STATUS TO provides a mechanism for uniquely identifying a tobacco product, and is the source of the SPTOBID variable. For more information on this domain, see section 3.1.1, Tobacco Product Identifiers and Descriptors. Only one tobacco product was of interest in the study.
These product malfunctions and events are represented in the Tobacco Product Events and Malfunctions Domain (EM). Events not specifically associated with the product device should not be represented in this EM domain.
The sponsor used a standardized or dictionary-derived text for the description of an issue or events. CDISC does not prescribe what standardized or dictionary-derived text should be used.
The sponsor decided to use the International Medical Device Regulators Forum (IMDRF) document “IMDRF Terminologies for Categorized Adverse Event Reporting (AER): Terms, Terminology Structure and Codes. Annex A ( 2022) provides the medical problem codes. The name and version of the dictionary used to map terms must be provided in a Define.XML ExternalCodeList element (See Section 2.10 Standards for Data Exchange).
EMDECOD was the Level 3 IMDRF term. Non-standard variables were used to represent the various coding level variables defined in the dictionary.
Example SUPPEM Variable Metadata

| EMIMDRCD | IMDRF Code | text | IMDRFANNEXA |
| EMIMDRFL2 | IMDRF Level 2 | text | IMDRFANNEXA |
| EMIMDRFL1 | IMDRF Level 1 | text | IMDRFANNEXA |

The EM dataset is shown below.
Below is the dataset, SUPPEM, used to represent the non-standard variables 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.
In this study, Subject 3067 had an AE associated with the battery problem. This was reported in the AE dataset. Not all variables are shown below for brevity.
The RELREC dataset was used to record the relationship between the Tobacco Product Events and Malfunctions (EM) dataset and any reported AE represented in the AE dataset.
