title	Study 123, Report (for reference only, will be deleted?)

For the purposes of team review of the example data, the report is included in this section:

Sample data #1: Determination of the in vitro genotoxicity potential of 10 tobacco products in the in vitro Micronucleus Assay

Study info: This study was performed to assess the in vitro genotoxicity of 10 different tobacco products containing 1% to 2% nicotine. The genotoxic potential was determined using the in vitro micronucleus test with TK6 lymphoblastoid suspension cells. The study was conducted in compliance with the following documents:

OECD TG 487 (2010): Guideline for the testing of chemicals: In vitro mammalian cell micronucleus test.
BL SOP 132: Determination of the in vitro genotoxicity of condensates from tobacco products and ingredients for tobacco products / electronic vapour products – in vitro micronucleus test (IVM) with TK6 cells.

The cells were exposed to increasing dose levels of tobacco product using short term treatment in the presence and absence of an external metabolic activation system (ST+/-S9 mix) as well as a long term treatment in the absence of an external metabolic activation system (LT-S9 mix).

Toxicity was calculated as relative increase in cell count (RICC), relative cell count (RCC) and relative population doubling (RPD). RPD is the cytotoxicity measure used for the assessment. RICC and RCC are also reported but not considered for the assessment.

Note: OECD GUIDELINE FOR THE TESTING OF CHEMICALS

Population Doubling = [log (Post-treatment cell number ÷ Initial cell number)] ÷ log 2

Conclusion: All tobacco product evaluated did not induce any signs of severe toxicity or genotoxicity in any of the treatments and do not fulfil the criteria to be classified as genotoxic.

Reported results: (only listed the result of one tobacco product as an example)

Statistical analysis

Adjusted p-values calculated for the micronucleus frequencies for every dose level as compared to the corresponding solvent control after ST in the presence and absence of S9 mix as well as LT in the absence of S9 mix. One way ANOVA with posthoc Dunnett’s test for multiple comparisons for the dose response and a two tailed unpaired student’s t-test for the comparison of positive and negative control were used. The difference between the samples is considered statistically significant at p≤0.05.

Bleo: Bleomycin; CPA: Cyclophosphamid A; statistically significant increases are highlighted in bold.

title	ts.xpt (trial summary, study level parameters)

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
Assumption: SPDEVID and DUREFID should only be in TX (with the same value for all sets if there is only one device used)
Assumption: SPDEVID (sponsor defined device identifier) should be added at the trial set level (tx.xpt) - we can discuss if this should be in TS when there is only one device for a study
- This allows for studies where there are multiple products and different product(s) per trial set, one record for each product that is being tested in each particular trial set (tx.xpt)
Do we need to document anything about extraction process steps from the smoking machine to a test material for an assay (MNvit) (ie, rinsing a filter??)
Concentration = 0 is negative control, Bleo and CPA are positive controls - confirm
