This study aims to assess the quality of articles published in the leading orthopedic surgery journals, by measuring the relation between the impact factor and the number studies with a high level of evidence.
A literature review was performed of articles published in four previously selected journals. A score of journal evidence (RER - Relation between Randomized clinical trials and Systematic reviews) was calculated, considering the number of RCTs and SR published and the total number of full-text articles.
The selected journals were JBJS-Am, ASMJ, BJJ-Br and Arthroscopy, with Impact factors of 5.280, 4.362, 3.309 and 3.206 respectively in 2015. In the study, the RER Scores, in the same order, were 9.408, 6.153, 7.456 and 7.779.
The journal JBJS-Am is the best available source of information on orthopedic surgery from this point of view. It has the highest Impact Factor and clearly the highest RER Score. On the other hand, we could conclude that the number of published RCT and good quality SR is very low, with less than 10% of all the articles.
本研究旨在通过衡量影响因子与高水平证据研究数量之间的关系，评估主要骨外科期刊发表文章的质量。
对在之前选定的四种期刊上发表的文章进行文献综述。计算期刊证据评分（RER——随机临床试验与系统评价之间的关系），考虑发表的随机对照试验（RCT）和系统评价（SR）的数量以及全文文章的总数。
选定的期刊为《美国骨与关节外科杂志》（JBJS-Am）、《美国肩肘外科杂志》（ASMJ）、《英国骨与关节杂志》（BJJ-Br）和《关节镜杂志》，2015年的影响因子分别为5.280、4.362、3.309和3.206。在该研究中，相应顺序的RER评分分别为9.408、6.153、7.456和7.779。
从这一角度来看，《美国骨与关节外科杂志》（JBJS-Am）是骨外科领域最佳的可用信息来源。它具有最高的影响因子，且显然具有最高的RER评分。另一方面，我们可以得出结论，已发表的随机对照试验和高质量系统评价的数量非常少，占所有文章的比例不到10%。
