Table 10 Results table data fields.

From: An EPA database on the effects of engineered nanomaterials-NaKnowBase

 

Description

ResultID

Unique (within publication) numerical identifier for the result data

ResultType

Type of results reported (e.g. viability)

ResultDetails

Any optional notes about the result

ResultValue

Numeric value of the reported result

ResultApproxSymbol

Used to note when a measurement is above or below the physical detection limits of the methods or machinery used (e.g. >, <, =)

ResultUnit

The units of the reported value

ResultUncertainty

States what uncertainty type is reported with the value, such as standard deviation or a range.

ResultLow

Holds the values described by Result Uncertainty. For ranges, this field holds the lower endpoint. If the uncertainty only reports one value (such as standard deviation), this field holds that value.

ResultHigh

Holds the upper endpoint for values described by Result Uncertainty. Is left blank for uncertainties with only one value reported.

assay_AssayID

Reference to the Assay ID of the assay this result came from.

assay_publication_DOI

Reference to DOI of the assay’s source publication.

  1. This table was used to record the results of an assay. Each row in Results referenced an assay by DOI and ID. Since an assay could have multiple results, each row in Results was given an incrementing ID to serve as the primary key. The ResultName field specified what kind of result, or endpoint, was being reported (e.g. size, pH, mortality, LD50, etc.). ResultDetails included any additional information that ResultName could not capture. Finally, the seven fields used to capture raw and processed measurement data from the material table were used here to describe the result measurement or assessment.
