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

  • Schrack et al found that VO2 measurements by the COSMED K4b2 were not significantly different (p = 0.25) but highly correlated (r = 0.96) to traditional stationary gas exchange during steady-state walking.

    “In contrast, Schrack et al 20 found that VO 2 measurements by the COSMED K4 b 2 were not significantly different (p = 0.25) but highly correlated (r = 0.96) to a traditional, stationary gas exchange during steady-state walking.”

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.
