Promotion of Neurointervention to International Journal Based on Journal Metrics.

PURPOSE The aim is to provide evidence of the internationalization of Neurointervention based on journal metrics for articles published from 2011 to 2015. MATERIALS AND METHODS The following metrics and data were collected and analyzed with descriptive statistics: number of citable and non-citable articles; number of research articles (original papers) supported by grants; editorial board members' countries; authors' countries; citing authors' countries; source title of citing articles; two-year impact factor; total citations; and Hirsch index (h-index). Data were retrieved and analyzed from the journal homepage and Web of Science Core Collection in January 24, 2016. RESULTS There were 80 citable and eight non-citable articles from 2011 to 2015. Out of 31 original articles, nine had research funds (29.0%). Editorial board members are from five countries. The authors are from six countries. The top-ranking countries of citing authors were USA, Korea, and China. The two-year impact factors were 1.125, 0.923, and 0.931 from 2013 to 2015. H-index was 7. CONCLUSION It was possible to confirm the internationalization of Neurointervention based on journal metrics. New digital standards should be adopted for more rapid dissemination of journal content.
