The phrase "a valid anchor" is correct and usable in written English.
It can be used in contexts where you are discussing something that serves as a reliable reference point or support for an idea, argument, or concept.
Example: "In our research, we found that a valid anchor is essential for establishing a strong foundation for our hypothesis."
Alternatives: "a reliable reference" or "a sound basis".
The IFCC reference system for HbA1c represents the only valid anchor to implement standardization of the measurement.
A first consensus meeting was held in 2007 (9– 10), where it was decided that the new IFCC reference system for HbA1c represents the only valid anchor to implement standardization of the measurement, and that HbA1c results were to be reported worldwide in IFCC units (mmol/mol) and derived NGSP units, using the IFCC-NGSP master equation.
This threshold is therefore neither MIC, which can be estimated empirically from valid anchors (such as correctly functioning transition questions), nor the minimally detectable change, which can be estimated from a variety of distribution methods (although we favour the method described in Additional File 1[ 20, 32]), but a hybrid of these two properties.
Therefore, patient-rated CGI scales represent a valid example of a reference anchor [ 26, 34, 35].
Our results support the assumption that anchoring remains a valid explanation for systematically biased decisions within market contexts.
Importantly, however, the external anchor chosen must itself be a valid measure of clinical change.
However, we did not find a valid definition of a relevant change in both anchors.
TQs should not be used to anchor RMDQ MIC thresholds as these may not provide a valid proxy of change in the latent construct measured by the RMDQ but are primarily driven by pain.
The use of the max-flow, min-cut provides a valid partition even if multiple cuts are required to ensure a valid LCB due to branching in the anchor graph.
