Abstract

BACKGROUND

To study different aspects of original articles published in Medicina Clínica (Barcelona) over a 30-year period (1962-1992), with special emphasis on references.

METHODS

We selected 12 articles per year at 5-year intervals (1962, 1967, 1972, 1977, 1982, 1987, 1992) using a systematic sampling procedure. The following variables were assessed: number of authors, interval between acceptance of the manuscript and publication in the journal, total number of references, language, document type, and name of the journal.

RESULTS

The mean (+/- standard deviation) number of authors showed a statistically significant increase (ANOVA; F = 13.666; p = 0.0001) from 1.83 +/- 0.71 in 1962 to 6.41 +/- 1.97 in 1992. The interval between acceptance and publication decreased from 315.72 +/- 20.48 days in 1982 to 206.16 +/- 89.23 in 1992 (ANOVA, F = 6.074; p = 0.0058). A total of 1816 references were found (24.2 references per article). English was the language of publication most commonly found (76.76%) followed by Spanish (12.6%). There was a statistically significant increase in the use of references corresponding to English articles over the study period (chi 2 = 314.431; p = 0.0001). A significant change was also observed in the type of document use (chi 2 = 143.996; p = 0.0001); references from journals increased from 73.51% in 1962 to 91.40% in 1992. In addition, 50.46% of the articles were published in only 7.84% of the journals. Eight journals devoted to internal medicine (1.79% of all journals) included 23.46% of the references.

CONCLUSIONS

The number of authors has shown a significant increase during the study period. The time elapsed between acceptance and publication has decreased significantly. Spanish authors acquired information mostly from the English literature. Articles published in journals are also mostly used as references. A large percentage of references consisted of articles published in core general journals. These journals accumulate a remarkable percentage of the information.

摘要

背景

研究发表于《巴塞罗那临床医学院学报》（Medicina Clínica）30年期间（1962 - 1992年）的原创文章的不同方面，特别关注参考文献。

方法

我们采用系统抽样程序，每隔5年（1962年、1967年、1972年、1977年、1982年、1987年、1992年）每年选取12篇文章。评估以下变量：作者数量、稿件接受至在该期刊发表的间隔时间、参考文献总数、语言、文献类型以及期刊名称。

结果

作者的平均数量（±标准差）显示出统计学上的显著增加（方差分析；F = 13.666；p = 0.0001），从1962年的1.83 ± 0.71增加到1992年的6.41 ± 1.97。接受至发表的间隔时间从1982年的315.72 ± 20.48天减少到1992年的206.16 ± 89.23天（方差分析，F = 6.074；p = 0.0058）。共发现1816条参考文献（每篇文章24.2条）。最常使用的发表语言是英语（76.76%），其次是西班牙语（12.6%）。在研究期间，对应英文文章的参考文献使用量有统计学上的显著增加（卡方检验 = 314.431；p = 0.0001）。文献使用类型也观察到显著变化（卡方检验 = 143.996；p = 0.0001）；来自期刊的参考文献从1962年的73.51%增加到1992年的91.40%。此外，50.46%的文章仅发表于7.84%的期刊。8种内科专业期刊（占所有期刊的1.79%）包含了23.46%的参考文献。
