title: Contribution of Indian Psychiatrists to PubMed Listed Mental Health Literature During 1995-2013: an Exploratory Study.
abstract: BACKGROUND
  Contribution of Indian Psychiatrists as publications in peer-reviewed journals listed with PubMed and their impact has not been studied. The aim of this manuscript is to assess such contribution using a new article level metric measure. The relative citation ratio (RCR) has been used to assess the quality, quantity, and impact of research output of Indian Psychiatrists.
  
  
  METHODS
  Publications by Indian psychiatrists in PubMed during 1995-2013 were collected, their RCR and associated factors estimated. The nationality of the journals, type of manuscripts, PubMed Central (PMC) visibility and the type of the journals were factored in. The data collected was analyzed. Descriptive statistics, Chi-square tests, correlations, and linear regression were performed. P ≤ 0.05 was taken as significant.
  
  
  RESULTS
  Using the criteria set, 1914 manuscripts were identified. Of the 1914 manuscripts, 1007 were cited at least once and among this, 40.7% were listed with PubMed while of the 907 non-PMC listed manuscripts, only 180 were never cited (P = 0.000). Of the 1032 manuscripts published in Indian journals, 474 were never cited while 214 of the manuscripts published with non-India based journals were never cited even once (P = 0.000).
  
  
  CONCLUSIONS
  The difference in terms of manuscripts visibility in PMC, nationality of journals and article type in analysis indicate that there exists an innate difference between the cited and noncited manuscripts. The probable explanation behind this and its associated phenomenon are discussed.
