This included, for example, pro- and con-arguments for their assessment, reference to thematically similar areas and existing studies.
The earthquake damage assessment reference information is shown in Fig. 5 according to Guo et al. (2010) and the China Earthquake Administration (2010).
Reference Value: In human health risk assessment, reference values are doses that are not anticipated to cause adverse effects in humans and are developed based on a point of departure divided by uncertainty" or "adjustment" factors.
In ecological risk assessment, reference values are concentrations in environmental compartments (soil, sediments, or water) that are not anticipated to cause adverse effects for receptors in the environmental compartments.
In 77 patients both muscle strength assessment (reference standard) and results from the neurofilament ELISA (index test) were available.
A database that included scheduled medication, non-scheduled medication, and PRN medication used at the assessment reference date was constructed.
The preferred practice pattern is for the assessment to be signed off as complete as close to the assessment reference date as possible.
The RAI-MDS capthees the number of days of medication use in the seven-day period prior to the assessment reference date.
Finally, the time between the assessment reference date and the date the assessment was signed off as complete, was considered as a measure of efficiency in completing the assessment and of the appropriateness of assessment practices.
For example, a troublesome data quality finding is the tendency for a few facilities to have large gaps between the assessment reference date and the date the assessment is signed off as complete.
