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

  • miR-21 targets phosphatase and tensin homolog (PTEN).

    “miR-21 was shown to target peroxisome proliferator-activated receptor alpha (PPARα) [73] and phosphatase and tensin homolog (PTEN) [74,75], among others.”

    From Emerging Role of miR-21-5p in Neuron–Glia Dysregulation and Exosome Transfer Using Multiple Models of Alzheimer’s Disease (2022) · cites this paper as [75]

    The Discussion and Results passages concern PPARα-dependent uptake and degradation of β-amyloid in astrocytes, not miR-21 targeting PTEN. Searches for miR-21, PTEN, and phosphatase and tensin homolog found no passage addressing the claim. In the citing sentence, the PTEN clause is attached to [74,75], rather than the PPARα citation [73]. (LLM, conf=0.76)

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.
