Assumption: The intent of this dataset is to provide a summary of trial (study) information. This is not subject-level data.
Assumption: A Trial (study) can have more than one assay type
Assumption: ASSAYID value of ALL indicates that it applies to all assays in the study
BLEO & CPA - are positive controls, should this be included/where is this captured? — in results for the record / row?
Where is TK6 cell type? is this test system (see below)
needs to be allowed to vary down to the well level / result level
For the items highlighted in orange - what is the lowest level where this could vary? e.g. at the level of a well in a 96-well plate, or a slide vs. assay level vs. product level
Smoke Regime needs to be allowed to vary down to the well level / result level
run - also at result level
port - (smoking product on the machine, you assign a run number or port-number for multiple replicates depending on linear vs. rotary machines; machine bias), needs to be allowed to vary down to the well level / result level)
replicate - (e.g., multiple samples from one vial), could be a replicate per exposure (e.g., 3 plates, multiple analyses for exposure)
sample ID - typically a unique number assigned (at CRO) or supplied by sponsor - result level
Smoke fraction - result level (e.g.tpm particulate vs. gas gvp)

Study Title
Determination of the in vitro genotoxicity potential of 10 tobacco products in both the in vitro Micronucleus Assay and the in vitro Neutral Red Uptake
During CT definition/reviews will decide appropriate TXPARM and TXVAL; Treatment duration may be controlled; For now, we just include good example values based on our experience
Assumption: The Trial Sets (TX) domain provides the list of distinct sets of subjects having different experimental factors, treatment factors, inherent characteristics, or distinct sponsor designations as specified in the trial design.
