To account for possible instrument drift across multiple days, background-corrected fluorescence values for all strains were normalized so that the individual worm with the highest fluorescence reading in each experimental session had a relative fluorescence measurement of 1.
For instruments that measured across multiple domains, the report was included if a subtotal for mobility could be determined.
This procedure might also be used by others facing similar challenges of complex translation and adaptation situations, where multidimensional instruments are used across multiple care settings in multiple languages.
Phantoms in the context of multicenter clinical trials are not only needed for calibration, but are further needed to ensure that instrument performance is maintained across multiple research sites, each with different phantoms, instruments and operators.
This procedure might be used by others facing similar challenges of complex translation and adaptation situations in which multidimensional instruments will be used across multiple languages in multiple care settings.
In other words, in addition to their primary use for proof-of-principle studies, phantoms are used for benchmarking system performance and ensuring data consistency across multiple instruments and even vendors.
While the present research makes an important contribution by establishing uniform data standards across multiple interRAI instruments, the work to link these instruments to terminology systems in medical records has not been completed.
Previous studies of satisfaction with VA training have used data from the Learners' Perceptions Survey (LPS), a validated survey instrument that measures satisfaction across multiple domains.
Absolute quantification is also necessary for correlating protein expression data across different biological samples, as well as across multiple experiments, instruments and laboratories, thus supporting more quantitative and hypothesis-driven proteome research.
Partly toward this end, the Undergraduate Research Student Self-Assessment (URSSA) was developed as a common assessment instrument that can be compared across multiple UR sites within or across institutions.
