The Introduction explains that NDI cause-of-death classifications may disagree with expert adjudication using medical records and other available information. The Discussion reports substantial CHD and CVD misclassification and advises caution when using NDI alone to determine cause of death. This supports the cited sentence's point about limitations identified through comparison with direct review. (LLM, conf=0.94)

The Discussion reports that older participants were more likely to have a CHD death recorded by NDI when expert adjudicators found another cause. It does not support the added claim that this occurred especially in patients with multiple comorbidities; it instead says disagreement was less likely among participants with a history of CHD or CVD. The Discussion also reports similar overall mortality rates despite classification discrepancies, so the overestimation finding is best confined to older participants. (LLM, conf=0.88)

The Results report eight late deaths from accidents or suicide and a significantly higher rate of unnatural deaths than in the age-comparable Taiwanese population. The Importance of Unnatural Deaths section gives the combined accident-or-suicide mortality rate as more than twice that of the general population. The statement that this finding was not confirmed in the citing authors’ cohort is their own comparison, not a finding attributed to this source. (LLM, conf=0.93)

The Discussion (page unavailable) reports that sudden cardiac death remained the major cause of late death after tetralogy of Fallot repair.

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.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
