In spite of that, the core functionality was easily provided on both platforms, each of which perform identical functions using the same instrument definition XML file, thus demonstrating the viability of our instrument schema for defining an interactive measurement instrument independently of the instrument's actual implementation.
The Dietary Screening Tool (DST) has been validated as a dietary screening instrument for older adults defining three categories of potential nutritional risk based on DST score cutoffs.
Completion for an instrument was defined as having >80% item responses for the total FACT-G or having >50% item responses for FACT-G subscales, FKSI, and FKSI-DRS.
Using a quench-flow instrument, tetrapeptide complexes were made by mixing the tripeptide complexes with S-Met TC for defined time points on the millisecond scale.
The date on which the first LC-MS/MS was conducted for each instrument was defined as day one.
ROC-analysis was performed to evaluate the screening properties of the SSI, and the cutoff threshold for the instrument was defined by optimal trade-off between sensitivity and specificity (Youden's index [ 31]).
Based on the knowledge learned from these undertakings, the areas of focus for the survey instrument are defined and explained in Table 1.
This is further supported by the fact that high clinical validity for an instrument defined and tested in a patient population has often not been achieved in field studies in general populations [ 42].
One option could be, for example, to resort to a dictionary definition, with the Oxford English Dictionary (OED) offering: "any instrument of manual operation", where instrument is defined as an "object used for a given purpose".
