The Virtues of Correct Citation
Open accessAbstract
Scientific statements have to be supported by evidence. The usual way to do this in academic articles is by citing the literature—that is, by giving references. A reference citation is supposed to provide accurate underpinning for a statement and to represent the current state of research, or, in the case of a maverick opinion, to ensure it is recognizable as such. Reference to a published source allows the reader to probe more deeply into the subject and puts him or her in a position to judge the underlying evidence. Using references puts the author under a duty to formulate them precisely so as to reproduce the source publication accurately. The convention of reference citation is a constituent element of scientific texts; it distinguishes them from journalism and other forms of writing and gives their content a particular authority. The majority of readers will have more confidence in a referenced statement than in one without a reference, even without checking it. The choice and placing of references, however, are complex processes prone to error. The following mistakes can appear: The source does not support the statement, or does so only partially (“quotation errors”). The reference citation is placed in such a way that it is not clear which statement it relates to. The bibliographic data (authors, title, volume number, page numbers, or journal title) are incomplete or wrong (“citation errors”). This can make it difficult or impossible to find the source. Quotation errors are particularly problematic because it is difficult to spot them: Often the reader can only judge the accuracy of a reference if he or she has relevant specialist knowledge or takes the trouble to research the sources cited. Another form of referencing error, which will not be treated here, is plagiarism: In this case the source of information is knowingly suppressed and the statement is presented as the plagiarizing author’s own intellectual achievement (1).

Previous reviews noted that the original studies had different criteria for quotation errors and different methods to calculate the total quotation error rate.
“As noted by the authors of previous reviews,[5, 7–9] the original studies had different criteria for quotation errors and different methods to calculate the total quotation errors rate.”
From Accuracy of cited "facts" in medical research articles: A review of study methodology and recalculation of quotation error rate (2017) · cites this paper as [8]
In the discussion of quotation errors (page not available), the paper says definitions of errors were not homogeneous across studies, supporting the claim about different criteria. It does not say the studies used different methods to calculate the total quotation-error rate. (LLM, conf=0.85)
Experimental — accuracy not yet measuredPrevious reviews estimated that approximately 20 to 25% of assertions cited from original research articles are inaccurately quoted in the medical literature.
“Previous reviews estimated that approximately 20 to 25% of assertions cited from original research articles, or “facts,” are inaccurately quoted in the medical literature.”
From Accuracy of cited "facts" in medical research articles: A review of study methodology and recalculation of quotation error rate (2017) · cites this paper as [8]
The Quotation errors section reports a median error rate of 20% in a systematic review of references from biomedical journals, and the Conclusion describes an error rate of around 20%. The paper does not establish that this estimate applies specifically to assertions citing original research articles rather than references more generally. (LLM, conf=0.84)
Experimental — accuracy not yet measuredThe estimated 14.5% quotation error rate is approximately 5-10% lower than estimates reported in previous reviews.
“This estimate has a more specific definition of the “medical literature,” as original research articles, and is approximately 5–10% lower than estimates reported in previous reviews.[5, 7, 8]”
From Accuracy of cited "facts" in medical research articles: A review of study methodology and recalculation of quotation error rate (2017) · cites this paper as [8]
In a subsequent review of studies published through 2011, the mean quotation error rate was estimated at 19.7%.
“In a subsequent review of studies published through 2011, a similar quotation error rate mean was estimated at 19.7%.[8]”
From Accuracy of cited "facts" in medical research articles: A review of study methodology and recalculation of quotation error rate (2017) · cites this paper as [8]
This analysis included the same studies in the quantitative analysis as the other reviews, which used slightly different search procedures.
“This analysis included the same studies in the quantitate analysis as the other reviews,[5, 7, 8] which used slightly different search procedures.”
From Accuracy of cited "facts" in medical research articles: A review of study methodology and recalculation of quotation error rate (2017) · cites this paper as [8]
The ‘Quotation errors’ section describes this paper’s Medline search and its restriction to publications from 2008 onward to avoid double-counting studies in an earlier review. Neither that section nor the Conclusion addresses whether the citing document’s quantitative analysis included the same studies as other reviews using different search procedures. Searches for that comparison found no supporting passage in our copy. (LLM, conf=0.76)

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.
