Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The most frequently deregulated component of the p53 pathway is a homozygous deletion of the CDKN2A/ARF locus, occurring in approximately 60% of all glioblastoma cases.

    “The most frequently deregulated component of the p53 pathway is a homozygous deletion of the CDKN2A/ARF locus, which occurs in ~60% of all GBM cases (Figure 1) [22,23].”

    From The p53 Pathway in Glioblastoma (2018) · cites this paper as [23]

    In Instructions > Viewing and Interpreting the Results (page not specified), the paper says most CDKN2A alterations in its GBM example are homozygous deletions. It discusses CDKN2A as an RB-pathway gene, however, and does not establish that CDKN2A/ARF deletion is the most frequent p53-pathway alteration or occurs in approximately 60% of all GBM cases. Its 71% figure refers to alterations in any of three RB-pathway genes in the queried cases. (LLM, conf=0.88)

  • Publicly available gene expression data from a matched cohort of mCRPC was downloaded from cBioportal.

    “Publicly available gene expression data from a matched cohort established previously59 or mCRPC was downloaded from cBioportal (20 May 2021)94–96.”
  • IMP2 is genomically altered in over 2% of all cancers, which is above the baseline of random alterations in the average passenger genes.

    “IMP2 is genomically altered in over 2% of all cancers, which is above the baseline of random alterations in the average passenger genes (Figure 5A) [77,78,79].”

    From IMPlications of IMP2 in RNA Biology and Disease (2025) · cites this paper as [78]

    The ‘Performing Cross-Cancer Queries’ section explains how cBioPortal displays alteration frequencies across cancer types, but gives no result for IMP2. Searches for IMP2, IGF2BP2, the over-2% figure, and a passenger-gene baseline found no passage establishing the claimed comparison. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Genomic amplifications creating extra copies of IGF2BP2 occur in 9% of lung cancers.

    “Genomic amplifications creating extra copies of IGF2BP2 occur in 9% of lung cancers (Figure 5A) [77,78,79].”

    From IMPlications of IMP2 in RNA Biology and Disease (2025) · cites this paper as [78]

    The Viewing and Interpreting the Results section discusses copy-number amplification, but its examples concern ERBB2 in colorectal cancer and CDK4 in glioblastoma. Searches for IGF2BP2 and for a 9% amplification rate in lung cancer found no passage reporting the claimed finding. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • KRAS mutations are implicated in 25-30% of all human cancers, about 19% of non-small cell lung cancers, about 40% of colorectal cancers, and about 73% of pancreatic ductal adenocarcinoma cases.

    “KRAS mutations are implicated in 25–30% of all human cancers, about 19% of non-small cell lung cancers (NSCLCs), about 40% of colorectal cancers (CRCs), and about 73% of pancreatic ductal adenocarcinoma (PDAC) cases (Figure 1) [1,2].”

    From KRAS: Biology, Inhibition, and Mechanisms of Inhibitor Resistance (2024) · cites this paper as [2]

    The Instructions > Viewing and Interpreting the Results section describes how cBioPortal displays mutation frequencies, but does not report KRAS prevalence in all cancers, NSCLC, colorectal cancer, or PDAC. Searches for KRAS and the cited percentages found no passage in our copy supporting those figures. (LLM, conf=0.75)

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.
