To analyse the total number of newspaper articles citing the four leading general medical journals and to describe national citation patterns.
Quantitative content analysis.
SETTING/SAMPLE: Full 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).
Press citations of four medical journals (two American: and ; and two British: and ) in 22 newspapers.
British 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. 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.
British 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.
分析引用四大普通医学期刊的报纸文章总数，并描述国家引用模式。
定量内容分析。
设置/样本：2008 年至 2015 年间来自 LexisNexis 的 14 个国家的 22 种综合报纸的全文。这 14 个国家分为四个区域：美国、英国、西方世界（英国以外的欧洲国家以及澳大利亚、新西兰和加拿大）和世界其他地区（其他国家）。
四大医学期刊（美国的《新英格兰医学杂志》和《美国医学会杂志》，英国的《柳叶刀》和《英国医学杂志》）在 22 种报纸上的媒体引用量。
2008 年至 2015 年间，英国和美国报纸每周引用这四种分析期刊中的一些期刊约三次（每周平均引用 3.2 和 2.7 次）；来自其他西方国家的报纸每周引用一次（每周平均 1.1 次），来自世界其他地区的报纸每月引用一次（每月平均 1.1 次）。《纽约时报》的引用量超过了其他所有报纸（每周平均 4.7 次）。分析显示，日报媒体存在三种国家引用模式：美国报纸主要引用美国期刊（70.0%的引用），英国报纸主要引用英国期刊（86.5%），而其余被分析的报纸则更多地引用英国期刊而非美国期刊。在除美国和英国之外的几乎所有西方国家的报纸媒体中，《柳叶刀》是被引用最多的期刊。多元对应分析证实了国家模式，并表明超过 85%的引文数据变化保留在仅一个单一的新变量中：国家维度。
英国和美国报纸更经常引用这四种分析期刊，显示出对各自国家期刊的国内偏好；非英国和非美国的报纸显示出共同的国际引用模式。
