Although much medical knowledge comes from observational research, such studies are more prone to confounding and bias than others. This study was conducted to evaluate the adherence of the observational studies published in Iranian medical journals to the STROBE (strengthening the reporting of observational studies in epidemiology) statement.
In this cross-sectional study, we selected 150 articles of Iranian medical journals, using multistage sampling from Aug 2016 to Jun 2017. The reported items of the STROBE statement in the articles was determined and considered as the adherence of the articles to the statement. The adherence of the articles with different characteristics was compared.
The adherence of the articles to the statement varied from 24% to 68% with a mean score of 48%±9%. The lowest mean scores were found in the Result (36%) and Method (49%) sections. The adherence was significantly better in the articles published in the journals indexed in PubMed or Web of Knowledge (ISI) databases (<0.001) and those written by cooperation of the authors from other countries (=0.044).
The evaluated articles in our study had not adequately reported the items recommended by the STROBE statement. This indicates deficiency in key elements for readers to assess the validity and applicability of a study.
尽管许多医学知识来自观察性研究，但此类研究比其他研究更容易受到混杂因素和偏倚的影响。本研究旨在评估伊朗医学期刊上发表的观察性研究对STROBE（加强流行病学观察性研究报告）声明的遵循情况。
在这项横断面研究中，我们采用多阶段抽样方法，从2016年8月至2017年6月选取了150篇伊朗医学期刊文章。确定文章中STROBE声明报告的项目，并将其视为文章对该声明的遵循情况。比较了具有不同特征的文章的遵循情况。
文章对该声明的遵循率在24%至68%之间，平均得分为48%±9%。结果部分（36%）和方法部分（49%）的平均得分最低。在PubMed或Web of Knowledge（ISI）数据库索引的期刊上发表的文章（<0.001）以及由其他国家作者合作撰写的文章（=0.044）的遵循情况明显更好。
我们研究中评估的文章没有充分报告STROBE声明推荐报告的项目。这表明在读者评估研究的有效性和适用性的关键要素方面存在不足。
