The range and prevalence of problems with systematic reviews

Systematic review of published evidence investigating problems in the conduct or reporting of systematic reviews . These problems, errors, biases or influences may potentially be attributable to stakeholders, sponsors and publishers as well as individuals comprising the project team. They may also affect the reliability or validity of the systematic review conclusions.

This project aims to identify published evidence which examines these issues which could include systematic reviews, primary studies or meta-epidemiological analyses of systematic reviews. In order to avoid publication bias, grey literature from unpublished evidence will also be considered. Comprehensive bibliography searches will be used to search for relevant papers. Literature searches to expand thesaurus and free-text terms related to bias, misconduct or errors will also be complemented with pearl growing searches of relevant papers and contact with experts.

This project is funded through a UK Medical Research Council Career Development Award to Lesley Uttley, University of Sheffield.

对已发表的关于系统评价执行或报告过程中存在问题的实证研究进行系统综述。这些问题、错误、偏见或影响因素可能归因于利益相关者、赞助商和出版商，以及项目团队中的个人。这些问题也可能影响系统评价结论的可靠性和有效性。本项目的目标是识别已发表的关于这些问题的实证研究，这可能包括系统评价、原始研究或系统评价的元流行病学研究。为了避免发表偏倚，也将考虑未发表的灰色文献。为了寻找相关论文，将使用综合的文献检索方法。同时，为了扩展与偏见、不当行为或错误相关的术语表和自由文本术语，还将辅以相关论文的珍珠生长搜索以及与专家的联系。本项目由英国医学研究委员会对谢菲尔德大学的Lesley Uttley的职业发展奖资助。
