Our study aimed to evaluate the trends of post retraction citations of articles reporting a radiology-imaging diagnostic method and to find if a different pattern exists between manuscripts reporting an ultrasound method and those reporting other radiology diagnostic methods. This study reviewed retractions stored in PubMed on the subject of radiology-imaging diagnosis to identify the motivation, time from publication to retraction, and citations before and after retraction. The PubMed database was searched on June 2017 to retrieve the retracted articles, and the Scopus database was screened to identify the post-retraction citations. The full text was screened to see the type of post-retraction citation (positive/negative) and whether the cited article appears or not as retracted. One hundred and two retractions were identified, representing 3.5% of the retracted articles indexed by PubMed, out of which 54 were included in the analysis. Half of the articles were retracted in the first 24 months after publication, and the number of post retraction citations was higher than the number of citations before retraction in 30 out of 54 cases (US methods: 9/20, other diagnostic methods 21/34, P-value = 0.2312). The plagiarism was the most common reason for retraction (31%), followed by repetitive publication (26%), and errors in data/manuscript (24%). In less than 2% of cases, the retracted articles appear as retracted in the text or reference list, while the negative citation is observed in 4.84% among manuscripts reporting an US diagnostic method and 0.32% among manuscripts reporting a diagnostic method other than US (P-value = 0.0004). No significant differences were observed when post retraction weighted citation index (WCI, no. of citations weighted by citation window) was compared to WCI prior retraction (P-value = 0.5972). In light of the reported results, we enumerated some recommendations that could potentially minimize the referral to retracted studies as valid.
我们的研究旨在评估报道放射影像学诊断方法的文章在被撤回后的引用趋势,并确定报道超声方法与其他放射诊断方法的手稿之间是否存在不同的模式。本研究回顾了储存在 PubMed 中与放射影像学诊断相关的撤回研究,以确定撤回的原因、从发表到撤回的时间,以及撤回前后的引用。2017 年 6 月,我们在 PubMed 数据库中检索撤回的文章,并在 Scopus 数据库中筛选出撤回后的引用。我们对全文进行筛选,以确定撤回后的引用类型(正面/负面),以及引用的文章是否作为撤回文章出现。确定了 102 次撤回,占 PubMed 索引的撤回文章的 3.5%,其中 54 篇被纳入分析。一半的文章在发表后的头 24 个月内被撤回,在 54 篇文章中有 30 篇(US 方法:9/20,其他诊断方法 21/34,P 值=0.2312)撤回后的引用数量高于撤回前的引用数量。撤回的最常见原因是剽窃(31%),其次是重复发表(26%)和数据/手稿错误(24%)。不到 2%的情况下,在文本或参考文献列表中会显示撤回的文章,而在报道超声诊断方法的手稿中,观察到 4.84%的负面引用,在报道除超声以外的诊断方法的手稿中观察到 0.32%(P 值=0.0004)。与撤回前的加权引用指数(WCI,引用窗口加权的引用数)相比,撤回后的加权引用指数(WCI)没有显著差异(P 值=0.5972)。根据报告的结果,我们列举了一些建议,这些建议可以最大限度地减少将被撤回的研究作为有效研究进行引用。
