B - E-publication bias

Krag Jakobsen A, Christensen R, Persson R et al. And now, e-publication bias. BMJ 2010;340:c2243

In open access (OA) publishing scholarly communication is made available free 0f charge on the Internet. In biomedical research, authors or sponsors often pay a fee to a publisher to enable immediate free online access. Other journals use a hybrid model allowing authors to choose between subscription access and author-paid OA. Results from a study on OA publishing in a journal of the BMJ group show that author-paid OA publishing preferentially increases accessibility to studies funded by industry. For this emerging type of publication bias in OA hybrid journals, the term e-publication bias is suggested.
