All articles in 2009 continue to be free open access, with no charge to authors for publishing and no charge for readers to download full text content.
The full-text contents of all 31 papers, which included 26 original articles [ 14- 39] and five review articles [ 1, 2, 9, 10, 40], were reviewed and compared.
To avoid publication bias, we performed an extensive literature search to identify all papers published previously on the clinical usefulness of NSE and S-100B in prediction of prognosis after resuscitation from CA and closely reviewed the full-text contents of all papers thus identified.
The web contains much latent knowledge, especially when that knowledge is expressed as unstructured and poorly categorized full-text content.
If there was a link to full-text content from PMC or publisher web sites, the full-text was also perused.
We further refined retrieved items based on abstract and/or full-text content, and the number of patients (requiring n≥30 for diagnosis, monitoring, prognosis; n ≥ 10 for treatment).
The selection of literature for inclusion in the review was based on examination of abstracts and indexing (subject headings) where available, and on full text or the table of contents if accessible.
For example, ScienceDirect has a good full text search of all Elsevier content, but it does not search other publishers content.
Systematic review up to November 2004 of MEDLINE, EMBASE, Current Contents, and full-text journal content databases to identify RCTs stopped early for benefit.
Their review included trials with results published in MEDLINE, EMBASE, Current Contents, and full-text journal content databases up to November 2004.
