Explicar els conflictes d'interès dels autors d'articles a revistes científiques s'ha convertit en un requeriment cada vegada més estricte. Sorprèn que els mateixos que han demanat explicitar els conflictes d'interès als autors no ho hagin fet ells mateixos. Em refereixo, és clar, als editors de les revistes. I ara a Plos Medicine han posat el dit a la nafra. A més a més han relacionat el factor d'impacte amb qui finança la revista. El resum en dos paràgrafs:
The proportion of RCTs with sole industry support varied between journals. Thus, 32% of the RCTs published in the NEJM during both two-year periods had industry support whereas only 7% of the RCTs published in the BMJ in 2005–2006 had industry support. Industry-supported trials were more frequently cited than RCTs with other types of support and omitting industry-supported RCTs from impact factor calculations decreased all the approximate journal impact factors. For example, omitting all RCTs with industry or mixed support decreased the 2007 BMJ and NEJM impact factors by 1% and 15%, respectively. Finally, the researchers asked each journal's editor about their journal's income from industry sources. For the BMJ and The Lancet, the only journals that provided this information, income from reprint sales was 3% and 41%, respectively, of total income in 2005–2006.
These findings do not imply that the decisions of editors are affected by the possibility that the publication of an industry-supported trial might improve their journal's impact factor or income. Nevertheless, the researchers suggest, journals should live up to the same principles related to conflicts of interest as those that they require from their authors and should routinely disclose information on the source and amount of income that they receive.
El Plos Medicine fa l'exercici de transparència i diu el que costa:
Total income US$187,640.59 comprises US$ 179,220.00 in author fees, US$ 8339.81 of advertising and other revenue and US$ 80.78 in reprint revenues. PLoS's overall revenues for 2009 are listed in the 2009 Progress report http://www.plos.org/downloads/progress_update_lo.pdf.
I la pregunta és: qui està disposat a mossegar la mà que et dona de menjar?
