The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality. This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI).
Descriptive study at Brazilian Cochrane Center.
All the published articles were evaluated according to merit assessment (content) and form assessment (performance).
Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives.
These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.
运用严谨的科学方法有助于撰写方法学质量上乘的科学文章。这使得提高文章的引用率并增加影响因子成为可能。巴西期刊不得不适应这些索引机构要求的某些质量标准，比如每期发表的原创文章的内容和数量。本研究旨在评估巴西两份心脏病学领域的期刊在方法学上的适切性，这两份期刊被多个数据库收录，可通过科学电子图书馆在线平台（SciELO）免费获取，且目前已被科学引文索引（科学信息研究所，ISI）收录。
在巴西考科蓝中心开展的描述性研究。
根据价值评估（内容）和形式评估（表现）对所有已发表文章进行评估。
所分析的文章中有96%呈现出适合回答研究目的的研究设计。
这两份巴西心脏病学领域的期刊发表的文章在方法学上是适切的，因为它们遵循了质量标准。因此，这些期刊既可供查阅，也可作为发表未来文章的载体。为了进行进一步分析，必须应用其他科学活动指标，如文献计量学（评估信息的生产、传播和使用的定量方面）和科学计量学（也涉及科学政策的制定，它常常与文献计量学重叠）。
