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
Sponsor should be "applicant", how do we represent this? In text explanation in the IG? In definition in CT/Parmcd/Parm? ** Need to have CT discussion, include Erin M.**
TK6, human keratinocyte, is this the "test system"?
Can we draft a starting list of Study Types and Sub Types to submit to CT now?
Is there a dictionary of species and/or strain that we would use? (see example)

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~~ applicant designations as specified in the trial design.
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
Where are the details of the smoke regime defined/submitted today? (e.g., puff profile = Bell shaped puffing volumes; Puff Block = 50%, etc.)
Smoke fraction? is this indicator of processing of material from smoke machine..we used Smoke Exposure System - ok?
Incubate cells (37 ºC ±1 ºC, 90% ±10% humidity, and 5% ±1% CO2/air) - these are ranges, do we model for ranges?
