The Institute of Medicine of the National Academy of Sciences in the USA has put forward an evaluation scheme for biomarkers, looking at validation (assay performance), qualification (assessment of evidence of association), and utilisation (a description of the context in which the surrogate has utility).
Most recently the Institute of Medicine of the National Academy of Sciences in the USA has put forward an evaluation scheme for biomarkers, looking at validation (assay performance), qualification (assessment of evidence), and utilisation (the context in which the surrogate is to be used).
Separating the validity of the measurement, the qualification of the evidence of association, and the context or contexts in which the assumption of surrogacy is valid represents an important methodological statement that has worked well in this case, as it did in case studies in the report.
Retaining a level of freshness and zest represented a colossal challenge and, despite the near-misses in domestic cup competitions and the Fifa Club World Cup, he can now point to a significant trophy and Champions League qualification as evidence of proper success.
But we should also be very careful about oversimplifying the issue of aggregate teacher quality -- and making sweeping statements about their qualifications based on a limited body of evidence -- for the sake of intuitive, easy-to-understand talking points.
The process of qualification documents abundant evidence showing that endoscopic ulcers and serious upper gastrointestinal damage are influenced in the same direction and much the same magnitude by a variety of risk factors and interventions.
We therefore believe that our data add to the growing body of evidence to support the ongoing clinical qualification of these markers of liver injury.
(4) Evidence of the case manager's professional status: minimum higher professional qualification and maximum use of evidence-based interventions.
This study builds on previous studies and generates evidence that contributes to qualification of BSI as an imaging biomarker in prostate cancer patients.
"Just one university degree" in any subject was the necessary qualification, together with evidence of her "experience in translation or languages".
