This example will need to be updated following the ENDS stability study approach, which was created to reflect recent developments and consultation with CDISC ISMT |

NOTE TO TEAM REVIEWERS: The example below demonstrates the required data structure of one record per analyte per replicate per test condition per timepoint to accurately represent data from a stability study. The resulting structure would require 648 rows to illustrate the 12 analytes shown in the example study we received, done in triplicate under two test conditions at the number of timepoints in the example study. For conciseness, we have abbreviated the examples below to demonstrate the concepts as follows: First- we show all 12 analytes as a single replicate, at one time point and one test condition in order to illustrate the variables and terminology required to put together a stability study with assays done in replicate at different time points and varying test conditions, even though only one record per analyte is illustrated. Second- We show ONE analyte (moisture) in triplicate, over a series of time points and two test conditions to give a sense of what the complete data would look like. Hopefully users could combine the information shown in both examples to construct a complete dataset containing all the records for each analyte-replicate-test condition-time point group. |

DI = TO for Tobacco Product Identifiers and Descriptors SPDEVID = SPTOBID for Sponsor Tobacco Product Identifier DO/DU = Tobacco Product Design Parameters (PD) LB = Tobacco Product Testing (PT) - [Would Findings be better?] |
Shelf life study has a protocol and provides the results of shelf life studies of tobacco products over time with different conditions and analytes. Generally there are many conditions with at least two with varying temperature, humidity, etc.
The initial table shows the a number of the analytes and test conditions used in Shelf Life studies for smokeless tobacco products for one testing condition at one timepoint and one replicate. The second table has one analyte and two test conditions for many time points and replicates.
The Tobacco Product Testing (PT) is a Findings domain similar to the Laboratory Test Results domain.

Rows 1-9: | Show the PTTEST of Product Moisture for Condition 1 which is shown in PTTSTCND. The sample of various timepoints that may be used in the testing for product moisture is reflected in PTTPT. The PTTPTNUM shows the numerical version of the planned timepoint. The REPNUM shows the incidence number of a test that is repeated within a given timeframe for the same test. | Rows 10-18: | Show the PTTEST of Product Moisture for Condition 2 across the same timepoints shown for Condition 1. The PTGRPID is used to tie together a block of related records in a single domain. | |

Finally, the The storage conditions details of "E-Liquid Standard (Long Term) Condition 1" and "E-Liquid Standard (Long Term) Condition 1" .Details of the storage conditions are represented in the Environmental Storage Conditions (ES) dataset.
- The variable STOCONID (Storage Condition ID) = "E-Liquid Standard (Long Term) Condition". Each of the parameters defining that storage condition are represented in ESPARMCD/ESPARM, with values and units shown in ESVAL/ESVALU.These values were made up, but we assume they'd look something like this.
