InVitro Neutral Red Cytotoxicity Assay Results Example 1

This example shows trial design and results data for in vitro Neutral Red Cytotoxicity Assay, Relative Absorbance.

Note that Variable Names and Domain abbreviations may change (have not been checked against existing and are not vetted)

red font - indicates potential for CT code lists
green font - links to other domains
purple font - remaining questions to resolve

The following shows the tabulated data as it is represented in a report for this study. This report includes summary statistics (e.g. Average, Standard Deviation, Coeff. Var.); however, statistics are not included in the SEND standard and will not be represented in the SEND domains example.

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?
TK6, human keratinocyte, is this "test system"?
Can we draft a starting list of Study Types and Sub Types to submit to CT now?

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.
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
