title: Impact factor of Indian Journal of Gastroenterology for the years 2005 and 2006.
abstract: OBJECTIVE
  To determine the impact factor (IF) of the Indian Journal of Gastroenterology (IJG) for the years 2005 and 2006.
  
  
  METHODS
  For each of the two years, the number of citations received during that year in the journals included in the Science Citation Index (SCI), obtained by searching the online SCI database, divided by items published in the IJG in the previous two calendar years was determined. Self-citations in the IJG of the items published during the preceding two calendar years were determined by manual search. IF was calculated from these data.
  
  
  RESULTS
  The IF of IJG for the year 2005 was 0.384 and that for the year 2006 was 0.667. The latter may be an underestimate because some citations during the year 2006 may not yet have appeared in the database. These values were higher than the previously reported IF of IJG of 0.192 in 1990.
  
  
  CONCLUSIONS
  The IF of IJG has shown significant improvement over time.
