  The following journal metrics were analyzed from the journal's homepage or the Web of Science: the number of citable articles, number of countries of affiliation of the contributors, the number of articles supported by research grants, total citations, impact factor, citing journals, countries of citing authors, and the Hirsch index.
  
  
  RESULTS
  The number of citable articles in 2011, 2012, 2013, and 2014 was 22, 81, 120, and 95, respectively. The authors were from 11 countries. Twenty-one out of 55 original articles were supported by research grants. The total citations in 2012, 2013, and 2014 were 2, 85, and 213, respectively. The impact factor was 0.670 in 2013 and 0.940 in 2014. The number of countries citing authors were from was 61. The Hirsch index was 6.
