National citation patterns ofNEJM,The Lancet,JAMAandThe BMJin the lay press: a quantitative content analysis

Abstract

ObjectivesTo analyse the total number of newspaper articles citing the four leading general medical journals and to describe national citation patterns.DesignQuantitative content analysis.Setting/sampleFull text of 22 general newspapers in 14 countries over the period 2008–2015, collected from LexisNexis. The 14 countries have been categorised into four regions: the USA, the UK, Western World (European countries other than the UK, and Australia, New Zealand and Canada) and Rest of the World (other countries).Main outcome measurePress citations of four medical journals (two American: NEJM and JAMA; and two British: The Lancet and The BMJ) in 22 newspapers.ResultsBritish and American newspapers cited some of the four analysed medical journals about three times a week in 2008–2015 (weekly mean 3.2 and 2.7 citations, respectively); the newspapers from other Western countries did so about once a week (weekly mean 1.1), and those from the Rest of the World cited them about once a month (monthly mean 1.1). The New York Times cited above all other newspapers (weekly mean 4.7). The analysis showed the existence of three national citation patterns in the daily press: American newspapers cited mostly American journals (70.0% of citations), British newspapers cited mostly British journals (86.5%) and the rest of the analysed press cited more British journals than American ones. The Lancet was the most cited journal in the press of almost all Western countries outside the USA and the UK. Multivariate correspondence analysis confirmed the national patterns and showed that over 85% of the citation data variability is retained in just one single new variable: the national dimension.ConclusionBritish and American newspapers are the ones that cite the four analysed medical journals more often, showing a domestic preference for their respective national journals; non-British and non-American newspapers show a common international citation pattern.

Microbiome research in general and business newspapers: How many microbiome articles are published and which study designs make the news the most?

“…The factors associated with greater levels of newspaper coverage for scientific papers have also been studied. They include the prestige of the journal [ 17 ], the availability of press releases [ 18 – 22 ], the domestic preference of newspapers for journals from their own country [ 23 ], and the newsworthiness of the topic [ 24 ].…”

“…Despite the current scientific interest in the microbiome, its social impact in newspapers has not been properly analyzed. One relevant way of studying the subject is by analyzing the number of newspaper articles in which authors, papers or journals are cited (called “press citations”) [ 18 , 23 , 30 ]. As such, our first objective was to analyze the extent to which the predictable increase in the number of microbiome papers in recent years has had a parallel impact in the press, in both general and business newspapers, given the potential for harnessing the human microbiome to prevent, diagnose or cure disease.…”

A bibliometric analysis and review of recent researches on TRPM7

“…Citations of medical journals by other journals are important for scientific publications. They are applied to calculate the impact factors of journals, which are viewed as a proxy for the scientific relevance and influence of an academic community [15]. From the TRPM7 paper with the most cited times over the past 15 years, they found that TRPM7 serves as a MLKL (Mixed Lineage Kinase Domain-like) downstream target to mediate Ca 2+ influx and TNF-induced necroptosis, which reveals the critical mechanism of MLKL-mediated necroptosis [16].…”

Retos y perspectivas en el ecosistema de la información biomédica

“…El valor noticioso de la información es un factor importante pero no es un buen predictor de lo que acaba convirtiéndose en noticia. La publicación de una noticia de biomedicina obedece a una serie de factores, entre los que se cuentan la existencia de una nota de prensa asociada (De-Semir, 1998;Schwartz et al, 2012;Yavchitz et al, 2012;Casino, 2015;Sumner et al, 2016), la relevancia científica de la información (Repiso; Chaparro-Domínguez, 2018) y un factor nacional que prima la difusión de la investigación de un país en los medios nacionales Rius;Cobo, 2017). Pero la lista completa de factores asociados con la cobertura periodística y la importancia relativa de cada uno, en particular el peso de los intereses económicos y profesionales asociados a la información, está lejos de ser comprendida.…”
