Lisa Bero, Kellia Chiu, Quinn Grundy

BMJ 2019; 367: l6202 doi: https://doi.org/10.1136/bmj.l6202 (Published 18 December 2019)

Objectives 目的

To identify and calculate the prevalence of spin in studies of spin.

确定并计算有关倾向性陈述研究中倾向性陈述的比例

Design 试验设计

Meta-research analysis (research on research).

meta研究分析(对于研究的研究)

Setting 场景

35 studies of spin in the scientific literature.

科学文献中35项有关倾向性陈述的研究

Main outcome measures 主要预后指标

Spin, categorised as: reporting practices that distort the presentation and interpretation of results, creating misleading conclusions; discordance between results and their interpretation, with presentation of favourable conclusions that are not supported by the data or results; attribution of causality when study design does not support it; and over-interpretation or inappropriate extrapolation of results.

倾向性陈述分为:曲解结果表达与解读的行为,造成对结论的误导;结果及其解读的不一致,所表达的阳性结论并未得到数据或结果的支持;在试验设计并不支持的情况下推断因果关系;对于试验结果的过度解读或不适当推断。

Results 结果

Five (14%) of 35 spin studies contained spin categorised as reporting practices that distort the presentation and interpretation of results (n=2) or categorised as over-interpretation or inappropriate extrapolation of results (n=3).

35项有关倾向性陈述的研究中5项(14%)含有倾向性陈述,分别是对于结果表达与解读的曲解(n=2)或对于结果的过度解读或不适当推断(n=3)。

Conclusion 结论

Spin occurs in research on spin. Although researchers on this topic should be sensitive to spinning their findings, our study does not undermine the need for rigorous interventions to reduce spin across various research fields.

有关倾向性陈述的研究也出现倾向性陈述的情况。尽管这一问题的研究者应当对于倾向性陈述自身研究结果的行为保持敏感性,但我们的研究并不反对以下需求,即我们需要积极努力减少各个研究领域的倾向性陈述行为。

Conclusion with spin

带有倾向性的结论

Our hypothesis that spin will be less prevalent in spin studies than in studies on other topics has been proven. Spin scholars are less likely to spin their conclusions than other researchers, and they should receive substantial resources to launch and test interventions to reduce spin and research waste in reporting.

我们证实了研究假设,即与其他领域的研究相比,有关倾向性陈述的研究较少出现倾向性陈述行为。与其他研究者相比,倾向性陈述研究专家更少对自身研究结论进行倾向性陈述,因此应当得到更多资源实施并验证干预措施,以减少结果报告中的倾向性陈述。
