SDTM Example.Product HPHC Cigarette Testing

Tobacco product HPHC testing results are represented in the PT domain. This example assumes testing at a single time point, not serial testing over multiple timepoints as in stability studies. See the Stability Studies section for more information and examples illustrating how to represent those data.

This example only shows test results for each constituent for one replicate of one sample of one product that was tested (PTREPNUM = 1 for all records). Details of the sampling and testing plan, including the number of samples of the products tested, are determined by the sponsor or by regulatory requirement.  Sponsors would likely have multiple product samples tested in multiple replicates, and those would be distinguished in the dataset by values of PTREPNUM being set to 1 through n, where n = the number of replicates being performed.

Note the use of the PTXFN (external file name) to indicate that the lab methodology was submitted as separate documentation.

The identifying characteristics of the smoking machine are represented in the Device Identifiers reference dataset. DI is the source of the sponsor-defined device ID variable (SPDEVID) used in the PT dataset to indicate the smoking machine used to perform the smoking regimen.
