the conclusions were based on data from PubMed&#46; Given the enormous volume of articles about this infection that have literally inundated the biomedical literature&#44; it seems difficult to conceive of finding only 254 publications by Spanish authors during the specified study period of February 1&#44; 2020&#44; to January 1&#44; 2021&#46; As I write today &#40;February 24&#44; 2022&#41;&#44; I find 103<span class="elsevierStyleHsp" style=""></span>707 articles using the same search strategy in titles that Mi&#241;ones-Ginarte et al&#46; used&#58; the search terms were <span class="elsevierStyleItalic">SARS-CoV-2</span>&#44; <span class="elsevierStyleItalic">COVID-19</span>&#44; <span class="elsevierStyleItalic">skin</span>&#44; <span class="elsevierStyleItalic">cutaneous</span>&#44; and <span class="elsevierStyleItalic">dermato</span>- separated by the Boolean operator OR&#46; When the descriptor Spain was added to the affiliation field&#44; the number of articles fell to 3813&#46; Clearly&#44; that figure is far from the 330 publications Mi&#241;ones-Ginarte et al&#46; reported finding and the 254 publications they analyzed in their study&#46;</p><p id="par0010" class="elsevierStylePara elsevierViewall">In addition&#44; the authors classified the publications into 2 categories&#44; one that contributes direct clinical knowledge &#40;case reports and case series&#41; and another with articles that make no contribution to direct clinical knowledge&#46; This classification is highly questionable and lacks interest&#46; Given the strict requirements of scientific quality required by MEDLINE&#47;PubMed before journals are indexed in the database&#44;<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">2</span></a> all studies included are relevant&#44; not just those labeled case reports&#46; What does it mean&#44; for example&#44; that the authors did not include articles indexed as clinical studies or clinical trials among those making direct clinical contributions&#63; In my opinion&#44; the criteria used to categorize these articles were in error&#44; unless the authors&#8217; aimed to study only case reports when quantifying Spanish contributions to COVID-19 knowledge&#46; An inappropriate study design undermines the validity of any research and casts doubt on a study&#39;s scientific interest&#46;<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">3</span></a> Also unjustified was the authors&#8217; use of free search terms rather than medical subject headings &#40;COVID-19&#44; SARS-CoV-2&#44; and dermatology&#44; etc&#46;&#41;&#46; Finally&#44; the authors&#8217; most important mistake was that they generalized from a sample of 254 articles&#44; adjusting for population &#40;per 100<span class="elsevierStyleHsp" style=""></span>000 population&#41; and countries&#8217; COVID-19 case and mortality rates in order to make comparisons&#46; The decision to do so was scientifically flawed given the issue of data accuracy and the well-known technical problems related to managing epidemiological data describing this disease&#46;<a class="elsevierStyleCrossRefs" href="#bib0070"><span class="elsevierStyleSup">4&#44;5</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">It is important to point out that methodological details of some of the cited studies are imprecisely reported&#44; a problem that necessarily undermines interpretation and can lead to false conclusions&#46;<a class="elsevierStyleCrossRefs" href="#bib0080"><span class="elsevierStyleSup">6&#44;7</span></a> For example&#44; the cited study by Haghani et al&#46;&#44;<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">8</span></a> which is based on data from Scopus&#44; gives the information for Spain in a supplementary table that corresponds to publications on coronaviruses in general&#44; not specifically the one that causes COVID-19&#46;</p><p id="par0020" class="elsevierStylePara elsevierViewall">When Spain was said to be in 15th place in general bibliometric studies according to the cross-sectional study of Liu et al&#46;&#44;<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">9</span></a> there were 3 Spanish publications out of a total of 550 that appeared over the course of 10 weeks&#44; meaning that the percent visibility of Spain&#39;s research in that sample was 0&#46;5&#37;&#46; According to another cited study&#44;<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">10</span></a> Mi&#241;ones-Ginarte et al&#46;<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">1</span></a> reported that Spain ranked in seventh place &#40;though in fact it was eighth place&#41; or ninth &#8220;depending on which database was being analyzed&#8221;&#42; but they do not mention that the articles analyzed by the authors of that study were exclusively preprints found in a variety of online platforms&#46;</p><p id="par0025" class="elsevierStylePara elsevierViewall"><span class="elsevierStyleItalic">Actas Dermo-Sifiliogr&#225;ficas</span> has always been a journal of reference&#44; implicitly invested in scientific quality&#46; It is one that occupies a unique and unchallenged position among solid&#44; prestigious journals in Spain&#46; Possibly the journal&#39;s rigorous peer review process should have been applied to the scientific letter by Mi&#241;ones-Ginarte et al&#46;<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">1</span></a> None of these criticisms call into question the fact that Spanish dermatologists indisputably contributed to the advance of science in their specialty before and during the pandemic&#44;

    "textoCompleto" => "<span class="elsevierStyleSections"><p id="par0005" class="elsevierStylePara elsevierViewall">I read with interest the results of the bibliometric study by Mi&#241;ones-Ginarte et al&#46;&#44;<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">1</span></a> which concluded that Spanish dermatology has played a brilliant role in generating direct clinical knowledge during the pandemic caused by SARS-CoV-2 infection&#59; the conclusions were based on data from PubMed&#46; Given the enormous volume of articles about this infection that have literally inundated the biomedical literature&#44; it seems difficult to conceive of finding only 254 publications by Spanish authors during the specified study period of February 1&#44; 2020&#44; to January 1&#44; 2021&#46; As I write today &#40;February 24&#44; 2022&#41;&#44; I find 103<span class="elsevierStyleHsp" style=""></span>707 articles using the same search strategy in titles that Mi&#241;ones-Ginarte et al&#46; used&#58; the search terms were <span class="elsevierStyleItalic">SARS-CoV-2</span>&#44; <span class="elsevierStyleItalic">COVID-19</span>&#44; <span class="elsevierStyleItalic">skin</span>&#44; <span class="elsevierStyleItalic">cutaneous</span>&#44; and <span class="elsevierStyleItalic">dermato</span>- separated by the Boolean operator OR&#46; When the descriptor Spain was added to the affiliation field&#44; the number of articles fell to 3813&#46; Clearly&#44; that figure is far from the 330 publications Mi&#241;ones-Ginarte et al&#46; reported finding and the 254 publications they analyzed in their study&#46;</p><p id="par0010" class="elsevierStylePara elsevierViewall">In addition&#44; the authors classified the publications into 2 categories&#44; one that contributes direct clinical knowledge &#40;case reports and case series&#41; and another with articles that make no contribution to direct clinical knowledge&#46; This classification is highly questionable and lacks interest&#46; Given the strict requirements of scientific quality required by MEDLINE&#47;PubMed before journals are indexed in the database&#44;<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">2</span></a> all studies included are relevant&#44; not just those labeled case reports&#46; What does it mean&#44; for example&#44; that the authors did not include articles indexed as clinical studies or clinical trials among those making direct clinical contributions&#63; In my opinion&#44; the criteria used to categorize these articles were in error&#44; unless the authors&#8217; aimed to study only case reports when quantifying Spanish contributions to COVID-19 knowledge&#46; An inappropriate study design undermines the validity of any research and casts doubt on a study&#39;s scientific interest&#46;<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">3</span></a> Also unjustified was the authors&#8217; use of free search terms rather than medical subject headings &#40;COVID-19&#44; SARS-CoV-2&#44; and dermatology&#44; etc&#46;&#41;&#46; Finally&#44; the authors&#8217; most important mistake was that they generalized from a sample of 254 articles&#44; adjusting for population &#40;per 100<span class="elsevierStyleHsp" style=""></span>000 population&#41; and countries&#8217; COVID-19 case and mortality rates in order to make comparisons&#46; The decision to do so was scientifically flawed given the issue of data accuracy and the well-known technical problems related to managing epidemiological data describing this disease&#46;<a class="elsevierStyleCrossRefs" href="#bib0070"><span class="elsevierStyleSup">4&#44;5</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">It is important to point out that methodological details of some of the cited studies are imprecisely reported&#44;
