Background
Degenerative cervical myelopathy (DCM) is a recently proposed umbrella term for symptomatic cervical spinal cord compression secondary to degeneration of the spine. Currently literature searching for DCM is challenged by the inconsistent uptake of the term ‘DCM’ with many overlapping keywords and numerous synonyms.Objectives
Here, we adapt our previous Ovid medline search filter for the Ovid embase database, to support comprehensive literature searching. Both embase and medline are recommended as a minimum for systematic reviews.Methods
References contained within embase identified in our prior study formed a ‘development gold standard’ reference database (N = 220). The search filter was adapted for embase and checked against the reference database. The filter was then validated against the ‘validation gold standard’.Results
A direct translation was not possible, as medline indexing for DCM and the keywords search field were not available in embase . We also used the ‘focus’ function to improve precision. The resulting search filter has 100% sensitivity in testing.Discussion and Conclusion
We have developed a validated search filter capable of retrieving DCM references in embase with high sensitivity. In the absence of consistent terminology and indexing, this will support more efficient and robust evidence synthesis in the field. 相似文献2.

Searching for health information is a core activity for health library and knowledge workers, whether seeking to support health care workers in overcoming barriers to accessing drug information, exploring the potential of text mining in developing search filters, translating search filters for use on alternative databases, or the importance of updating search filters to ensure their ongoing utility. 相似文献

Background:Literature searches underlie the foundations of systematic reviews and related review types. Yet, the literature searching component of systematic reviews and related review types is often poorly reported. Guidance for literature search reporting has been diverse and, in many cases, does not offer enough detail to authors who need more specific information about reporting search methods and information sources in a clear, reproducible way. This document presents the PRISMA-S (Preferred Reporting Items for Systematic reviews and Meta-Analyses literature search extension) checklist, and explanation and elaboration.Methods:The checklist was developed using a three-stage Delphi survey process, followed by a consensus conference and public review process.Results:The final checklist includes sixteen reporting items, each of which is detailed with exemplar reporting and rationale.Conclusions:The intent of PRISMA-S is to complement the PRISMA Statement and its extensions by providing a checklist that could be used by interdisciplinary authors, editors, and peer reviewers to verify that each component of a search is completely reported and, therefore, reproducible. 相似文献

Objective:The aim of this project was to validate search filters for systematic reviews, intervention studies, and observational studies translated from Ovid MEDLINE and Embase syntax and used for searches in PubMed and Embase.com during the development of evidence summaries supporting first aid guidelines. We aimed to achieve a balance among recall, specificity, precision, and number needed to read (NNR).Methods:Reference gold standards were constructed per study type derived from existing evidence summaries. Search filter performance was assessed through retrospective searches and measurement of relative recall, specificity, precision, and NNR when using the translated search filters. Where necessary, search filters were optimized. Adapted filters were validated in separate validation gold standards.Results:Search filters for systematic reviews and observational studies reached recall of ≥85% in both PubMed and Embase. Corresponding specificities for systematic review filters were ≥96% in both databases, with a precision of 9.7% (NNR 10) in PubMed and 5.4% (NNR 19) in Embase. For observational study filters, specificity, precision, and NNR were 68%, 2%, and 51 in PubMed and 47%, 0.8%, and 123 in Embase, respectively. These filters were considered sufficiently effective. Search filters for intervention studies reached a recall of 85% and 83% in PubMed and Embase, respectively. Optimization led to recall of ≥95% with specificity, precision, and NNR of 49%, 1.3%, and 79 in PubMed and 56%, 0.74%, and 136 in Embase, respectively.Conclusions:We report validated filters to search for systematic reviews, observational studies, and intervention studies in guideline projects in PubMed and Embase.com. 相似文献

通过实例从使用他人原始科研数据撰写论文,发现存在受试人群样本量、抽样单位不真实,或更换调查工具但调查时间不符合逻辑和调查时间与采用的研究工具编制时间矛盾等方面问题。本文以《护理学报》为例探讨科技期刊编辑对调查研究类稿件隐性学术不端行为的审核要点,并提出防范对策和建议。对于调查研究类稿件,编辑应在稿件的初审、二审阶段进行源文献挖掘,从选题、样本量、伦理审核、调查工具选择、资料收集方法和时间、数据统计及结果分析等方面全面审核稿件的逻辑性及科学性,判断稿件是否存在潜在学术不端行为。建议科技期刊编辑部为调查研究类稿件匹配相应领域的编辑和审稿专家,期刊编辑重视加强自身学习及与稿件作者的沟通,从而有效防范隐性学术不端行为。 相似文献

ABSTRACTThis article presents a thorough bibliometric analysis of research published in Annals of Library and Information Studies (ALIS), an India-based journal, for the period 2011–2017. Specifically, it compares this journal’s trends with those of other library and information science (LIS) journals from the same geographical area (India, and Asia as a whole) and with the 10 highest-rated LIS journals worldwide. The source of the data used was the multidisciplinary database Scopus. To perform this comparison, ALIS’ production was analyzed in order to identify authorship patterns; for example, authors’ countries of residence, co-authorship trends, and collaboration networks. Research topics were identified through keyword analysis, while performance was measured by examining the number of citations articles received. This study provides substantial information. The research lines detected through examining the keywords in ALIS articles were determined to be similar to those for the top LIS journals in both Asia and worldwide. Specifically, ALIS authors are focusing on metrics, bibliometrics, and social networking, which follows global trends. Notably, however, collaboration among Asia-based journals was found to be lower than that in the top-indexed journals in the LIS field, showing lesser internationalization. The results obtained present a roadmap for expanding the research in this field. 相似文献

The March 2017 issue of the Health Information and Libraries Journal marks the 10 year anniversary of the inaugural review published in the journal's review series. The review series was conceived to meet the growing appetite of health library and information workers to access synthesised evidence to inform their practice; something we'd already been doing to support medics in their practice. This editorial looks back on the 10 years and the inspiration which saw the development of a typology of review types and associated methodologies to address the lack of consistent guidelines on the features a review should incorporate. 相似文献
