将研究结果忠实地提炼成摘要可能具有挑战性。在字数限制和调查人员的激情之间，结果可能会被歪曲，过分强调好处或低估危害，有时被称为“旋转”。自旋更常在随机试验的摘要中描述，包括研究肥胖的试验（1），但在总结系统综述和荟萃分析（以下简称SRMA）的结果时可能会有所不同。例如，Yavchitz和其他人在SRMA中定义了多种形式的旋转，包括不适当地建议转化为临床实践和选择性报告安全性结局等（2）。由于SRMA综合了肥胖研究的结果，其摘要可能会影响利益相关者对证据的解释，因此应该清楚而忠实地报告，而不应进行旋转。但SRMA结果在肥胖研究中包含旋转的频率有多高？Faulkner等人得出结论，10%的肥胖SRMA摘要包含自旋（3）。在上下文中，他们的团队成员在其他领域发表了至少14项关于SRMA抽象自旋流行率的其他调查。表1显示，来自肥胖SRMA的摘要包含第二低比例的自旋。从绝对意义上讲，我们希望在更少的SRMA中看到旋转，而从相对意义上讲，肥胖作为一门学科似乎比其他领域做得更好。
Faithfully distilling study results into an abstract can be challenging. Between word limits and investigators’ passions, results may be misrepresented in ways that over emphasize benefits or underemphasize harms, sometimes referred to as ‘spin.’Spin has more often been characterized in abstracts of randomized trials, including those studying obesity (1), but may manifest differently when summarizing the results of systematic reviews and metaanalyses (hereafter, SRMAs). Yavchitz and others, for instance, defined multiple forms of spin in SRMAs, including inappropriately recommending translation to clinical practice and selective reporting of safety outcomes, among others (2). Because SRMAs synthesize findings on obesity research, their abstracts can impact stakeholders’ interpretation of evidence, and should be reported clearly and faithfully without spin.But how often do SRMA results contain spin in obesity research? Faulkner et al. concluded that 10% of obesity SRMA abstracts contained spin (3). Put in context, members of their team have published at least 14 other investigations of SRMA abstract spin prevalence in other domains. Table 1 shows that abstracts from obesity SRMAs contained the second lowest proportion of spin. In absolute terms, we would like to see spin in fewer SRMAs, while in relative terms, obesity as a discipline seems to be doing well against other fields.
