title: [Methods of statistical analysis in psychiatric publications].
abstract: In order to evaluate the use of statistical methods, authors analyzed the articles in the "Korsakoff Journal of Neurology and Psychiatry" 2007-2008 (351 articles) and the "Social and Clinical Psychiatry" 2007 (73 articles). The data were compared to the results of the similar Russian study performed 15 and 20 years ago and the English-language study performed 25 years ago. It has been concluded that the share of articles without any statistical data analysis has decreased dramatically, the use of tables and graphs has become obligatory, t-test has become one of the most used (without any explication of its usage in many cases). Russian publications remain behind English-language articles in using statistical methods.
