期刊的影响因子(IF)和总引用次数通常用作其出版物质量的指标。此外,要求作者遵守报告指南或进行试验注册的期刊通常具有较高的报告质量.在这项研究中,我们试图探索实施报告指南或试验注册与外科杂志的IF或总引文之间的潜在关联,以寻找新的方法和思路来提高杂志的发表质量.
我们检查了2018年期刊引文报告的扩展科学引文索引中的外科期刊,以量化报告指南或研究注册的使用。我们回顾了每个期刊的“作者指南”,并使用多变量线性回归分析来确定哪些指南与期刊IF和总引用相关。因变量是2018年IF的对数底数10或2018年总引用数的对数底数10(结果以几何平均值表示,特别是“认可组”结果与“未认可组”结果的比率)。独立变量是要求之一(认可和未认可)。模型针对发布区域进行调整,语言,开始年,出版商和期刊大小(仅用于调整总引用次数)。
我们在研究中纳入了188种外科期刊。多元线性回归分析结果显示,期刊IF与以下要求相关(P<0.01):随机对照试验(RCT)注册(几何均值比(GR)=1.422,95%CI[1.197-1.694])。合并报告试验标准(CONSORT)声明(1.318,[1.104-1.578]),系统评价荟萃分析(PRISMA)报表的首选报告项目(1.390,[1.148-1.683]),加强流行病学观察研究报告(STROBE)声明(1.556,[1.262-1.919]),诊断准确性报告标准(STARD)声明(1.585,[1.216-2.070]),流行病学观察性研究(MOOSE)声明(2.113,[1.422-3.133])。我们发现认可RCT注册之间存在关联(GR=1.652,95%CI[1.268-2.153]),CONSORT(1.570,[1.199-2.061]),PRISMA(1.698,[1.271-2.270]),STROBE(2.023,[1.476-2.773]),STARD(2.173,[1.452-3.243]),和MOOSE语句(2.249,[1.219-4.150])和总引用次数。
报告指南和试验注册的存在与外科期刊中更高的IF或更多的总引用相关。如果更多的外科期刊将这些政策纳入其提交要求,这可以提高出版质量,从而增加他们的IF和总引文。
A journal\'s impact factor (IF) and total citations are often used as indicators of its publication quality. Furthermore, journals that require authors to abide by reporting guidelines or conduct trial registration generally have a higher quality of reporting. In this study, we sought to explore the potential associations between the enforcement of reporting guidelines or trial registration and a surgical journal\'s IF or total citations in order to find new approaches and ideas to improve journal publication quality.
We examined surgical journals from the 2018 Journal Citation Report\'s Expanded Scientific Citation Index to quantify the use of reporting guidelines or study registration. We reviewed the \"instructions for authors\" from each journal and used multivariable linear regression analysis to determine which guidelines were associated with the journal IF and total citations. The dependent variable was the logarithm base 10 of the IF in 2018 or the logarithm base 10 of total citations in 2018 (the results were presented as geometric means, specifically the ratio of the \"endorsed group\" results to \"not endorsed group\" results). The independent variable was one of the requirements (endorsed and not endorsed). Models adjust for the publication region, language, start year, publisher and journal size (only used to adjust total citations).
We included 188 surgical journals in our study. The results of multivariable linear regression analysis showed that journal IF was associated (P < 0.01) with the following requirements: randomized controlled trial (RCT) registration (geometric means ratio (GR) = 1.422, 95% CI [1.197-1.694]), Consolidated Standards of Reporting Trials (CONSORT) statement (1.318, [1.104-1.578]), Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) statement (1.390, [1.148-1.683]), Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement (1.556, [1.262-1.919]), Standards for Reporting Diagnostic Accuracy (STARD) statement (1.585, [1.216-2.070]), and Meta-analysis of Observational Studies in Epidemiology (MOOSE) statement (2.113, [1.422-3.133]). We found associations between the endorsement of RCT registration (GR = 1.652, 95% CI [1.268-2.153]), CONSORT (1.570, [1.199-2.061]), PRISMA (1.698, [1.271-2.270]), STROBE (2.023, [1.476-2.773]), STARD (2.173, [1.452-3.243]), and MOOSE statements (2.249, [1.219-4.150]) and the number of total citations.
The presence of reporting guidelines and trial registration was associated with higher IF or more total citations in surgical journals. If more surgical journals incorporate these policies into their submission requirements, this may improve publication quality, thus increasing their IF and total citations.
