Controlled Clinical Trials

Continued as Contemporary Clinical Trials. Contemporary Clinical Trials is an international peer reviewed journal that publishes manuscripts pertaining to all aspects of clinical trials, including, but not limited to, design, conduct, analysis, regulation and ethics. Manuscripts submitted should appeal to a readership drawn from disciplines including medicine, biostatistics, epidemiology, computer science, management science, behavioural science, pharmaceutical science, and bioethics. Full-length papers and short communications not exceeding 1,500 words, as well as systemic reviews of clinical trials and methodologies will be published. Perspectives/commentaries on current issues and the impact of clinical trials on the practice of medicine and health policy are also welcome. Contemporary Clinical Trials is unique in that it is outside the confines of disease specifications, and it strives to adapt and grow with an expanding clinical trials landscape as the needs of clinical research evolve in today's dynamic healthcare environment. Having taken upon the important role as a platform for knowledge exchange between experts in different disciplines related to clinical trials, the ultimate goal of Contemporary Clinical Trials is to advance this field of research for the benefit of patients.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

External Cites per Doc

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.

Estimated APC

It estimates the article processing charges (APCs) a journal might charge, based on its visibility, prestige, and impact as measured by the SJR. It does not reflect the actual APC, but rather a calculated approximation based on journal quality.

Year	Est. APC (USD)
1999	3513
2000	3524
2001	3529
2002	3505
2003	3541
2004	3567
2005	3567
2006	3590
2007	3667

Estimated financial value

It represents the potential financial worth of a journal. It is obtained by multiplying the journal's Estimated APC by the total number of citable documents published over the past five years. This value reflects the hypothetical revenue a journal could generate based on its estimated publication costs and scholarly output.
