作者：

Highlights：

• During the period 2004–2013 more than 7.3 million journal articles were added in PubMed, a 48.9% increase from 2003.

• Recently launched journals showed the greater annual increase in published articles, but, overall, older journals contributed most of the articles.

• The change in open access articles was higher than subscription access (80.8% vs 54.7%) from 2004 to 2013.

• Asian (114%) and European (34.9%) first author affiliation increased at a higher rate than American publications (7.9%).

• English remained the predominant language of publications. USA- and England-based organizations published a gradually increasing body of literature.
