- The clinical parallel: HbA1c transforms a noisy, moment-to-moment raw signal (blood glucose, which swings with every meal) into a feature — average glycaemic exposure over roughly three months — that exposes the regularity a clinician actually needs (chronic control) and discards the irrelevant minute-to-minute variation.
This sourceEstablishes that HbA1c reflects average glycaemic exposure over roughly the preceding months rather than moment-to-moment glucose, supporting HbA1c as the chronic-control decision feature.
SupportedVerified against the publisher's abstract
Nathan and colleagues report that the A1C assay "measures chronic glycemia" and is used to judge the adequacy of diabetes treatment and adjust therapy. Their study compares A1C at the end of three months against average glucose over the previous three months across 507 subjects, finding a linear relation. That integration of a fluctuating glucose signal into a roughly three-month measure of chronic control is what the sentence attributes to HbA1c. The feature-engineering framing, that HbA1c transforms a raw signal and discards minute-to-minute variation, is the article's; the work notes that day-to-day management is guided separately by self-monitoring of capillary glucose.
“The A1C assay, expressed as the percent of hemoglobin that is glycated, measures chronic glycemia and is widely used to judge the adequacy of diabetes treatment and adjust therapy.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
