Quality of scientific articles Qualidade de artigos científicos * Moyses Szklo Department of Epidemiology. Bloomberg School of Public Health. The Johns Hopkins Medical Institutions. Baltimore, MD, USA Correspondence ABSTRACT The paper discusses the difficulties in judging the quality of scientific manuscripts and describes some common pitfalls that should be avoided when preparing a paper for submission to a peer-reviewed journal. Peer review is an imperfect system, with less than optimal reliability and uncertain validity. However, as it is likely that it will remain as the principal process of screening papers for publication, authors should avoid some common mistakes when preparing a report based on empirical findings of human research. Among these are: excessively long abstracts, extensive use of abbreviations, failure to report results of parsimonious data analyses, and misinterpretation of statistical associations identified in observational studies as causal. Another common problem in many manuscripts is their excessive length, which makes them more difficult to be evaluated or read by the intended readers, if published. The evaluation of papers after their publication with a view towards their inclusion in a systematic review is also discussed. The limitations of the impact factor as a criterion to judge the quality of a paper are reviewed. Keywords: Editorial policies. Peer review, research. Evaluation, standards. Publications, standards. Scientific publications. RESUMO O artigo discute as dificuldades em julgar a qualidade de manuscritos científicos e descreve algumas das armadilhas comuns que devem ser evitadas ao preparar um artigo para submissão a um periódico. A revisão por pares é um sistema imperfeito, com confiabilidade abaixo da ideal e validade duvidosa. Entretanto, como provavelmente continuará sendo o principal processo de seleção de artigos para publicação, os autores devem evitar alguns erros
