Vlassov V V. Is Content of Medical Journals Related to Advertisements? Case-control Study. Croat Med J. 2007;48:786-90
doi:10.3325/cmj.2007.6.786
A case-control study was performed on a convenience sample of 7 journals subscribed by Central Medical Library in Moscow, 4 international and 3 Russian peer-reviewed journals to assess the relationship between the content of the journal and paid advertisements published on the same journal. Study results showed that in 3 of 7 journals, contents were related to paid advertisements, usually placed somewhat explicitly face to face or overleaf the related research articles, supporting the hypothesis that journal content is manipulated to place more emphasis on the advertisements.
