The debate about the value of biomedical publications led to recommendations for improving reporting quality. It is unclear to what extent these recommendations have been endorsed by journals. We analyzed whether specific recommendations were included in author instructions, which journal characteristics were associated with their endorsement, how endorsement of the domains changed and whether endorsement was associated with change of impact factor between 2010 and 2015.
We considered two study samples consisting of "Hematology" and "Oncology" journals of the Journal Citation Report 2008 and 2014, respectively. We extracted information regarding endorsement of the (1) recommendations of the International Committee of Medical Journal Editors, of (2) reporting guidelines, (3) requirement for trial registration and (4) disclosure of conflicts of interest. Data extraction was done by reading the author instructions before conducting a text search with keywords. We calculated a global generalized linear mixed effects model for endorsement of each of the four domains followed by separate multivariable logistic regression models and a longitudinal analysis. We defined endorsement as the author instructions saying that they approve the use of the recommendations.
In 2015, the ICMJE recommendations were mentioned in author instructions of 156 journals (67.5%). CONSORT was referred to by 77 journals (33.3%); MOOSE, PRISMA, STARD and STROBE were referred to by less than 15% of journals. There were 99 journals (42.9%) that recommended or required trial registration, 211 (91.3%) required authors to disclose conflicts of interest. Journal impact factor, journal start year and geographical region were positively associated with endorsement of any of the four domains. The overall endorsement of all domains increased between 2010 and 2015. The endorsement of any domain in 2010 seemed to be associated with an increased impact factor in 2014.
Hematology and oncology journals endorse major recommendations to various degrees. Endorsement is increasing slowly over time and might be positively associated with the journals' impact factor.
关于生物医学出版物价值的争论促使人们提出了提高报告质量的建议。目前尚不清楚这些建议在多大程度上得到了期刊的认可。我们分析了作者指南中是否包含特定建议、哪些期刊特征与这些建议的认可相关、各领域的认可情况如何变化，以及2010年至2015年间认可与影响因子的变化是否相关。
我们考虑了两个研究样本，分别由《期刊引证报告》2008年和2014年的“血液学”和“肿瘤学”期刊组成。我们提取了关于以下方面认可情况的信息：（1）国际医学期刊编辑委员会的建议；（2）报告指南；（3）试验注册要求；（4）利益冲突披露。在进行关键词文本搜索之前，通过阅读作者指南来提取数据。我们针对四个领域中的每一个领域的认可情况计算了一个全局广义线性混合效应模型，随后进行了单独的多变量逻辑回归模型和纵向分析。我们将认可定义为作者指南表示批准使用这些建议。
2015年，156种期刊（67.5%）的作者指南中提到了国际医学期刊编辑委员会的建议。77种期刊（33.3%）提及了CONSORT；提及MOOSE、PRISMA、STARD和STROBE的期刊不到15%。有99种期刊（42.9%）推荐或要求进行试验注册，211种期刊（91.3%）要求作者披露利益冲突。期刊影响因子、期刊创刊年份和地理区域与四个领域中任何一个领域的认可呈正相关。2010年至2015年间，所有领域的总体认可有所增加。2010年对任何领域的认可似乎与2014年影响因子的增加相关。
血液学和肿瘤学期刊对主要建议有不同程度的认可。随着时间的推移，认可程度在缓慢增加，并且可能与期刊的影响因子呈正相关。
