Supplemental data for: A bibliometric assessment of the incidence of amyloid-Eszett (Aß), a false positive of amyloid-beta (Aβ), in the neurodegenerative disease literature

<p>One claimed reason for the development of Alzheimer&rsquo;s disease (AD), a prominent neurodegenerative disease, is the extracellular aggregation of amyloid-beta (A&beta;). A linguistic or formatting error has resulted in the misrepresentation of the Greek letter &beta; with the German letter Eszett (&szlig;), resulting in the formation of a non-existent compound, amyloid-Eszett (A&szlig;). These datasets offer a quantified appreciation of the AD-related literature, carrying a mention of this false positive in the title, abstract and keywords of papers indexed in the Web of Science Core Collection and Scopus. Also, as a curiosity given the popularity of this large language model, we asked the questions to ChatGPT. This AI chatbot developed by OpenAI was able to recognize Eszett as a linguistic or typographic error, within this context, recognizing A&szlig; and A&beta; as equals. This erroneous substitution of a Greek letter (in A&beta;) by a German one (A&szlig;), despite giving a non-existent compound, will likely not change the underlying scientific conclusions of the affected papers, although errata might be useful to enlighten others, including metadata managers and journal copyeditors, so as not to repeat the same mistake.</p>
