Letter to the Editor: Impact factor of Pakistani medical journals

Madam, the present era has witnessed an up-surge in the research trends in Pakistani medical community. This includes not only an increased number of articles being published but also creation of new journals.1 Unfortunately, there is paucity of quality medical journals from Pakistan, which can be appreciated from the fact that of the over 50 biomedical journals, only 4 are indexed by MedLine. Moreover, even lesser number of journals have an impact-factor (IF). IF is considered as an instrument of assessing the quality of a journal and its provided by Thomson Scientific, USA. IF is primarily dependent on the citations a journal receives for its articles.
