The first dataset shows 22 constituents each as a single replicate, at one time point and from one set of storage conditions in order to illustrate the variables and terminology required to construct an SDTM-conformant PT dataset for a stability study. Some constituent names (Values of PTTESTCD/PTTEST) appear multiple times because they are tested separately in both e-liquid and aerosol (as indicated by PTSPEC). Note that the constituent names shown do not represent an exhaustive list of the controlled terminology that will be developed to support representation of stability studies in SDTM.
