SEND Example.In vitro Neutral Red Cytotoxicity Assay

This example shows a report table, trial design, TOBA-78 - Getting issue details... STATUS and results data for the in vitro neutral red uptake (NRU) cytotoxicity assay TOBA-333 - Getting issue details... STATUS in example study 123.

The following shows example data for study 123 in a report table. This report includes summary statistics (i.e., average, standard deviation, coefficient variation) for each plate and an EC50 TOBA-593 - Getting issue details... STATUS value for the entire assay. In the table below, the light grey shading for plate 1 are values from wells that do not contain the NHK cells. The dark grey shading represents the column and row location within the 96-well plate, and in this example the applicant chose to use these column and row locations to assign their REFID values in the RELREF dataset and GT dataset.

For brevity, the datasets in this example are not comprehensive but are intended to demonstrate a range of proper use.

Row 1:	Shows the REFID of 123NRU that indicates the entire assay.
Rows 2, 5, 8, 9:	Show the REFIDs at the second level, all within the parent assay of 123NRU (REFID values of 1-3b, 1-3, 1-10, 2-10) which have LVLDESC of OBSERVATIONAL UNIT. If this study had recorded summary statistics for an entire trial set (e.g., across both plates for the same dose level), there would be an additional REFID for the trial set (with a LVLDESC of TRIAL SET).
Rows 3-4, 6-7, 10-11:	Show REFID values that the applicant chose, in this case, to represent the plate number (1 or 2), column (1 - 12), and row (A-G) of the 96-well plates.
Rows 3-4:	Show the REFIDs 1-3-A and 1-3-H that indicate two experimental units within the parent trial set of 1-3b.
Rows 6-7:	Show the REFIDs 1-3-B and 1-3-C that indicate two experimental units within the parent trial set of 1-3.
Row 10:	Shows the REFID of 1-10-G that indicates the experimental unit within the parent trial set of 1-10.
