Table_1_Most Common Publication Types of Neuroimaging Literature: Papers With High Levels of Evidence Are on the Rise.docx

Objective: This study evaluated the bibliometric data of the most common publication types of the neuroimaging literature.Methods: PubMed was searched to identify all published papers with “neuroimaging” as their MeSH Major Topics, and they were further searched by the following publication types: case report, clinical trial, comparative study, editorial, evaluation study, guideline, meta-analysis, multicenter study, randomized controlled trial, review, technical report, and validation study. The proportion of papers belonging to each publication type published in neuroimaging journals was calculated. Year-adjusted mean citation counts for each publication type were computed using data from Web of Science. Publication trend and its correlation with citation performance were assessed.Results: Review and comparative study were the most common publication types. Publication types with the highest proportion in neuroimaging journals were guideline, validation study, and technical reports. Since the year 2000, multicenter study, review, and meta-analysis showed the strongest linear increase in annual publication count. These publication types also had the highest year-adjusted citation counts (4.7–10.0). Publication types with the lowest year-adjusted citation counts were editorial and case report (0.5–1.0). It was estimated that 12.5% of the publications labeled as case reports were incorrectly labeled.Conclusions: Neuroimaging literature has been expanding with papers of higher levels of evidence, such as meta-analyses, multicenter studies, and randomized controlled trials.

研究目的：本研究评估了神经影像学文献中最常见出版物类型的文献计量数据。研究方法：通过PubMed数据库检索以“神经影像学”作为其MeSH主要主题的所有已发表论文，并进一步按以下出版物类型进行检索：病例报告、临床试验、比较研究、社论、评估研究、指南、荟萃分析、多中心研究、随机对照试验、综述、技术报告和验证研究。计算了发表在神经影像学期刊中的每种出版物类型的比例。利用Web of Science数据计算了每种出版物类型的年度调整平均引用次数。评估了出版物趋势及其与引用绩效的相关性。研究结果：综述和比较研究是最常见的出版物类型。在神经影像学期刊中比例最高的出版物类型为指南、验证研究和技术报告。自2000年以来，多中心研究、综述和荟萃分析在年度出版物数量上表现出最强的线性增长。这些出版物类型也拥有最高的年度调整引用次数（4.7-10.0）。年度调整引用次数最低的出版物类型为社论和病例报告（0.5-1.0）。估计有12.5%的标称为病例报告的出版物被错误地标记。研究结论：神经影像学文献随着更高证据水平的论文，如荟萃分析、多中心研究和随机对照试验的增多而不断扩展。
