Abstract

The goal of diabetes treatment is to maintain good glycemic control, prevent the development and progression of diabetic complications, and ensure the same quality of life and life expectancy as healthy people. Hemoglobin A1c (HbA1c) is used as an index of glycemic control, but strict glycemic control using HbA1c as an index may lead to severe hypoglycemia and cardiovascular death. Glycemic variability (GV), such as excessive hyperglycemia and hypoglycemia, is associated with diabetic vascular complications and has been recognized as an important index of glycemic control. Here, we reviewed the definition and evaluated the clinical usefulness of GV, and its relationship with diabetic complications and therapeutic strategies to reduce GV.

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

  • Glycaemic variability complicates both the achievement of recommended glycated hemoglobin (HbA1c) and time in range (TIR) targets.

    “It also complicates both the achievement of recommended glycated hemoglobin (HbA1c) and time in range (TIR) targets [101, 102].”

    From Diabetic gastroparesis: pathophysiology and impact on insulin timing choices (2026) · cites this paper as [102]

    The ‘Time in range (TIR)’ section (page unavailable) identifies TIR as a clinical target and reports that it correlates with glycaemic variability. The Introduction (page unavailable) says strict HbA1c-based control can carry risks. Neither passage establishes that glycaemic variability makes the recommended HbA1c and TIR targets harder to achieve. (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.
