Each is checked against this paper’s own text: does it say what the citing paper says it does?
In Pcsk9-knockout mice, LDLR protein levels at the cell surface of hepatocytes and in whole tissue are increased, while ASGR1 levels are not affected.
“The data showed that, although LDLR protein levels at the cell surface of hepatocytes (IHC) and in whole tissue (WB) were increased in Pcsk9-KO livers, in accordance with (21), those of ASGR1 were not affected.”
From Asialoglycoprotein receptor 1 is a novel PCSK9-independent ligand of liver LDLR cleaved by furin (2021) · cites this paper as [21]
In “LDLR subcellular distribution is affected by sex in PCSK9 KO livers” (page unavailable), the paper reports increased LDLR in liver extracts from both sexes, but increased hepatocyte-surface LDLR only in knockout males, not females. The citation is attached to the LDLR comparison; the sentence presents the ASGR1 result as the citing authors’ own data, so ASGR1 is not assessed as a claim attributed to this source.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
