One indicator of the influence of a scientific journal is the extent to which its articles are cited by others. A widely applied measure in this regard is so-called journal impact factor, an index devised by Eugene Garfield1 to quantify the extent to which the articles of that journal are cited in other peer-reviewed publications. The impact factor is typically computed as the quotient A/B, whe...

Citations for randomized controlled trials (RCT) are important for the dissemination of study results. However, predictors of citations for RCTs have not been investigated. The study aimed to investigate the predictors of citations for RCTs in sepsis literature. RCTs that investigated the efficacy of treatment strategies on clinical outcomes in sepsis patients were included, and publication dat...

OBJECTIVE Our objective was to evaluate quality of conduct and reporting of published systematic reviews and meta-analyses in paediatric surgery. We also aimed to identify characteristics predictive of review quality. BACKGROUND Systematic reviews summarise evidence by combining sources, but are potentially prone to bias. To counter this, the Preferred Reporting Items for Systematic Reviews a...

I am delighted to announce that Bone & Joint Research (BJR), which was only established in 2012, has now received its first impact factor, which is 1.640. This is the first opportunity that the BJR has had to get an impact factor, as a journal must be registered in PubMed for at least three years. The journal impact factor is an independent measure calculated by Thomson Reuters in Philadelphia,...

O ne of the best parts of being a journal editor is talking with authors, reviewers, and readers. Face-to-face discussions with early career scientists are especially interesting and enlightening. In June we gave " Getting Published " presentations to two groups at the Genetics Society of America's (GSA) International Caenorhabditis elegans Meeting at UCLA. The attendees were mainly graduate st...

BACKGROUND Systematic reviews are important for informing clinical practice and health policy. The aim of this study was to examine the bibliometrics of systematic reviews and to determine the amount of variance in citations predicted by the journal impact factor (JIF) alone and combined with several other characteristics. METHODS We conducted a bibliometric analysis of 1,261 systematic revie...

The impact factor (IF) of an journal is a measure reflecting the average number of citations to recent articles published in the journal. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones. However it is not a perfect metric and has its own limitations. Journa...

Journal impact factor (IF) as a gauge of influence and impact of a particular journal comparing with other journals in the same area of research, reports the mean number of citations to the published articles in particular journal. Although, IF attracts more attention and being used more frequently than other measures, it has been subjected to criticisms, which overcome the advantages of IF. Cr...

BACKGROUND The purpose of this study was to identify associations between study sponsorship and the methodological quality and published outcomes of head and neck cancer randomized controlled trials (RCTs). METHODS We systematically searched MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials for qualified RCTs, evaluating journal impact factor (IF), Jadad score (m...

The Korean Journal of Parasitology (KJP) is the official journal of the Korean Society for Parasitology which is celebrating its 50th anniversary in 2009. To assess the contributions and achievements of the KJP, bibliometric analysis was conducted based on the citation data retrieved from 4 major databases; SCI, PubMed, Synapse, and Scopus. It was found that the KJP articles were constantly cit...
