Salami science / slicing refers to the much frowned upon practice of splitting or reanalysing data from a single study to generate as many publications as possible. As a general rule, most clinical trials generate a single, primary paper, which describes the primary outcome set out in the protocol and often some of the secondary outcomes or incidental findings. Slides are used to illustrate oral presentations at meetings, but organisers rarely provide guidance about how to prepare them. Publishers, journal editors and some authors have been quick to embrace the social media such as Twitter and Facebook that sprung up around 2004–2006. Some journals require details about the exact role of the sponsor or funder in the research and publication process. Nearly all journals that levy an article processing charge for publication require payment after acceptance. However, a few journals charge a submission fee. Open Access journals are free to read but usually charge authors an article processing charge.
