  • Premisecitation

    Premisecitation

    Swinnen et al.'s data show that a higher cut-off value identifies a larger proportion of patients with severe hypoglycaemia, increasing sensitivity but reducing specificity.

    “Their data also indicate that a higher cut-off value identifies a higher percentage of patients who suffer severe hypoglycaemia, i.e. it increases sensitivity, albeit at the expense of specificity.”

  • The paper relies on this without support.

    The appropriate purpose of a glucose alert value is to prevent clinically important hypoglycaemia rather than to estimate its frequency.

    “The issue is not to estimate the frequency of clinically important hypoglycaemia.It is to prevent clinically important hypoglycaemia.”

Claims other papers make about this one

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

  • The alert value of ≤70 mg/dL (≤3.9 mmol/L) is higher than the glycemic threshold for symptoms in nondiabetic individuals and those with well-controlled diabetes, so it generally allows time to prevent a clinical hypoglycemic episode and provides margin for limited accuracy of monitoring devices at low-glucose levels.

    “Because it is higher than the glycemic threshold for symptoms in both nondiabetic individuals and those with well-controlled diabetes (9,13,14), it generally allows time to prevent a clinical hypoglycemic episode and provides some margin for the limited accuracy of monitoring devices at low-glucose levels.”
  • The alert value of ≤70 mg/dL is data driven and pragmatic.

    “This alert value is data driven and pragmatic (14).”
  • Because the alert value is higher than the glycemic threshold for symptoms in nondiabetic individuals and those with well-controlled diabetes, it generally allows time to prevent a clinical hypoglycemic episode and provides some margin for the limited accuracy of monitoring devices at low-glucose levels.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-04.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-04.

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.
