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 source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“Additionally, PEKK has a lower melt viscosity, making it easier to work with during printing. Furthermore, the printing temperature of PEKK is slightly lower than that of PEEK.”
From A comprehensive review of lunar-based manufacturing and construction (2024) · cites this paper as [217]
Experimental — accuracy not yet measuredThe cited source says what the claim attributes to it.
In the citing paper
“In comparison to PEEK, PEKK features an additional ketone group in its chemical structure.”
From A comprehensive review of lunar-based manufacturing and construction (2024) · cites this paper as [217]
The check wasn’t confident either way, so it gives no verdict — never disputed.
In the citing paper
“PEKK offers superior thermal stability, boasting a higher glass transition temperature (Tg) at around 162 ◦ C in contrast to PEEK, with a Tg of about 143 ◦ C.”

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.
