  • In both oxygen-generating examples, the oxygen generated by the device significantly enhanced the viability and function of the islets after transplantation.

    “In both these examples, the oxygen generated by the device significantly enhanced the viability and function of the islets after transplantation.”
  • Oxygen generating materials inserted alongside the islet graft improve oxygen levels at the transplantation site, and another strategy directly pumps oxygen into an encapsulation device.

    “To specifically improve oxygen levels at the transplantation site, oxygen generating materials have been inserted alongside the islet graft,96,98,99 while another strategy directly pumps oxygen into an encapsulation device92,97.”

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.
