Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Sympathetic denervation in POTS obstructs compensatory vascular constriction during upright posture, allowing blood pooling in splanchnic vasculature and lower extremities, leading to decreased venous return, sympathetic activation, and tachycardia.

    “Sympathetic denervation obstructs compensatory vascular constriction during upright posture, allowing blood to pool in the splanchnic vasculature and lower extremities [7;43;8]. The resulting decrease in venous return leads to the sympathetic activation and tachycardia of POTS.”
  • POTS patients may have orthostatic hypertension and complain of tremor, anxiety, and cold, sweaty extremities.

    “These patients may have orthostatic hypertension (increase in systolic blood pressure >10 mmHg on standing) and complain of tremor, anxiety and cold, sweaty extremities [7;25].”
  • Erythropoietin increases red cell mass and may stimulate vasoconstriction.

    “Erythropoietin increases red cell mass and may also stimulate vasoconstriction [7].”
  • Erythropoietin has potential adverse effects including myocardial infarction and stroke.

    “Potential adverse effects include vascular complications (myocardial infarction and stroke).”
  • A hyperadrenergic subtype of POTS has been proposed.

    “In opposite to the 'hypovolemic' subtype, another form of POTS, the 'hyperadrenergic' subtype was proposed [55].”

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.
