Studies were identified by searching Medline (1966 to May 2001), EMBASE/Excerpta Medica (1988 to March 2001), Pascal Biomed (1996 to February 2001), Current Contents (1997 to September 1999), PsycINFO (1966 to May 2001), the Cochrane Controlled Trial Register (last search May 15, 2001) and bibliographies of relevant textbooks and retrieved studies.
