Abstract

Purpose

To analyze the incidence of spin in the abstracts of systematic reviews and meta-analyses investigating anterolateral ligament augmentation or lateral extra-articular tenodesis as treatment for anterior cruciate ligament injuries.

Method

Studies were identified using the Preferred Reporting Items for Systematic Reviews and Meta Analysis guidelines searching PubMed, Web of Science, and Scopus in November 2023. The abstracts were graded for the incidence of the 15 most common types of spin, and full texts were reviewed for AMSTAR 2 classification. General demographics were identified, including study title, author, journal of publication, year of publication, level of evidence, study design, and funding. Fisher’s exact test was used to compare study metrics.

Results

Twenty-two studies met final inclusion criteria. Thirteen studies were related to LET, and 12 were related to ALL with three relevant to both. At least 4 forms of spin were observed in the studies with a maximum of 11 observed. Spin type 9 (“Conclusion claims the beneficial effect of the experimental treatment despite reporting bias.”) was the overall most reported across all studies with 21 out of 22 studies reporting it. There was a significant correlation between the incidence of spin type 10 (“Authors hide or do not present any conflict of interest.”) with lower Level of Evidence (P = .002). There is also a significant association with spin type 3 (“Selective reporting of or overemphasis on efficacy outcomes or analysis favoring the beneficial effect of the experimental intervention.”) with the “very low” category of AMSTAR 2 confidence (p = 0.034).

Conclusions

Spin is highly prevalent in abstracts of systematic reviews and meta-analyses investigating anterolateral ligament augmentation and lateral extra-articular tenodesis reconstruction.

Level of Evidence

Level IV, systematic review of Level III-IV studies.

旋转在前外侧韧带重建和外侧关节外肌腱固定术的系统综述和荟萃分析摘要中普遍存在

目的分析前交叉韧带损伤前外侧韧带增强术或外侧关节外肌腱固定术治疗的系统综述和荟萃分析摘要中旋转的发生率。方法在2023年11月检索PubMed、Web of Science和Scopus，使用系统评价和Meta分析指南的首选报告项目来确定研究。根据15种最常见自旋的发生率对摘要进行分级，并对全文进行AMSTAR 2分类。确定一般人口统计信息，包括研究标题、作者、发表期刊、发表年份、证据水平、研究设计和资金。Fisher的精确检验被用来比较研究指标。结果22项研究符合最终纳入标准。13项研究与LET相关，12项与ALL相关，3项与两者都相关。研究中至少观察到4种自旋形式，最多观察到11种。Spin类型9（“尽管报告存在偏见，但结论声称实验治疗的有益效果”）是所有研究中报道最多的，22项研究中有21项报道了它。自旋类型10（“作者隐藏或不存在任何利益冲突”）的发生率与证据水平较低之间存在显著相关性（P = 0.002）。自旋类型3（“选择性报告或过度强调疗效结果或有利于实验干预有益效果的分析”）与AMSTAR 2置信度“非常低”类别也存在显著关联（p = 0.034）。结论：在研究前外侧韧带增强术和外侧关节外肌腱固定术重建的系统综述和荟萃分析摘要中，spin是非常普遍的。证据水平：IV级，III-IV级研究的系统评价。
