Where this record's text came from. 2026-08-20 and 2026-08-26 schema-0.3 passes: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
How to read this page. The article itself is not reproduced here — this paper is not cleared for redistribution, so what follows is the tag layer alone. The evidence sentences are withheld with the article. The table at the foot lists every tag the record carries; each row names the facet it belongs to, and the whose words column says whether the tag records the paper's own wording or the tagger's sentence about the paper. Every tag links to each other paper in the corpus carrying it. The machine-readable edition of the same thing is the TEI file beside this one, where the tags live in standOff, and the article is at its publisher via the link below. When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.

Tags on this paper

Every tag the record carries, each linking to every other paper in the corpus that carries it. A tag appears here whether or not its words occur in the article — the spans below are only the ones a sentence in this paper licenses. Of the 19 concept tags on this paper, all 19 are grounded in a quoted sentence. 1 carry the tagger's gloss of what the term means in this paper, which is not something the article can license.

The paper

The full text is not reproduced here. This article is not cleared for redistribution, so the page carries the tag layer only. Its evidence sentences are withheld; the grounding status remains with each tag, and the article itself is at https://doi.org/10.1093/ageing/afy169. The reading view exists for the papers whose licence permits it.

Relations on this page carry a quotation for the claim. Where a relation was separately evidenced — and so tested against the vocabulary for its type — the row says so; none of 10 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.

mechanismsA REGIONAL FORK FIXED THE PARENT STANDARD AND THE PARENT ADOPTED THE FIX BACK: `Quotation withheld More recently, the Asian Working Group on Sarcopenia developed an EWGSOP-based consensus that specified cut-off points ... The cut-off points in the Asian consensus proved to be very useful ... Thus, EWGSOP2 has opted to provide recommendations for cut-off points.` A derived standard added what its parent left out, the addition worked, and the parent then took it back in - a fork and a merge in the history of one definition, both steps stated in one paragraph.

Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above.
A DEFINITION DAMAGED THE FIELD BY WHAT IT LEFT OUT. The 2010 consensus advised no cut-off points, and the paper says the resulting disputes HAMPERED RESEARCH AND DEVELOPMENT through lack of study consistency. The relation is between an ABSENCE in a definition and harm to a research literature, and there is no edge type for it - 'causes' would need the 'from' endpoint to be the missing thresholds, which are not a thing that existed

Quotation withheld — this record is not cleared for redistribution. The sentence is in the paper at the link above.
A SCREEN THAT MISSES WHAT THE PAPER WANTS FOUND. SARC-F has low-to-moderate sensitivity and very high specificity, so it 'will mostly detect severe cases' - and the stated purpose of the whole revision is EARLY detection. 'operationalised-as' asserts the instrument measures the construct; the true relation is that it measures one end of it, and the schema has no way to say which end

sensessarcopenia - THREE DATED SENSES, ALL THREE NAMED IN THIS ONE SENTENCE. Before 2010 the term meant low muscle MASS alone. EWGSOP 2010 added muscle FUNCTION, which the authors call `a major change at that time`. EWGSOP2 2018 puts muscle STRENGTH at the forefront because strength predicts adverse outcomes better than mass does. A study citing `sarcopenia` without a date is citing one of three different populations

sensesphysical performance - ONE VARIABLE, THREE ROLES, IN ONE SENTENCE. It was part of the core definition; other groups used it as an OUTCOME MEASURE, which makes it a dependent variable rather than a criterion; EWGSOP2 now uses it to grade SEVERITY.

senses[1]0.95the tagger's words
sensesprobable sarcopenia versus confirmed sarcopenia - A TWO-STAGE DIAGNOSIS AND THE STAGES REQUIRE DIFFERENT EQUIPMENT. Low strength alone makes it PROBABLE, which a dynamometer can establish anywhere; CONFIRMED needs muscle quantity or quality, which needs DXA, BIA, CT or MRI. So a prevalence figure depends on what machines the study had, and the design makes that explicit rather than hiding it

note: AUDIT CHANGED THIS FROM 'contradicts'. Mass is not rejected here and the paper never says the old criterion was wrong - mass is DEMOTED, from the primary parameter to the confirming one, on evidence that strength predicts adverse outcomes better.
