Abstract

Significance: Subcutaneous injections of insulin sustain life in mammals unable to produce insulin (type 1 diabetes) but do not prevent hyperglycemic and hypoglycemic swings or decrease hemoglobin A1c levels to normal amounts. In mice treated with insulin alone, repeated episodes of transient elevated blood glucose cause long-term damage. We show that in mice with type 1 diabetes treated with insulin, the transient high blood glucose levels require production of glucagon, a hormone that will cause the liver to produce more glucose. Blocking the action of glucagon with an antibody to the glucagon receptor completely normalizes blood glucose and hemoglobin A1c in the complete absence of insulin therapy. Suppressing glucagon action in combination with low-dose insulin would be a superior treatment for type 1 diabetes.

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

  • Only about 10% of active GLP-1 reaches the general circulation, and only a small fraction of that reaches the brain.

    “It is estimated that as little as 10% of active GLP-1 reaches the general circulation, and only a mere fraction of this reaches the brain63.”

    From Transforming obesity: The advancement of multi-receptor drugs (2024) · cites this paper as [63]

    The results passage reports circulating GLP-1 concentrations in control and antibody-treated mice, but not what proportion of active GLP-1 reaches the general circulation. Searches for the 10% estimate and for GLP-1 reaching the brain found no passage addressing either part of the claim (page numbers unavailable). (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.
