• Concerning figures: The preferred file format for figures are Word, Excel (data sheet and chart), or EPS files. While notes and sources can be integrated into the figure file (see style sheet), titles should not be integrated as they are typeset with the text and not with the graphic. Please download our stylesheet – including models - for the layout and formatting of figures here. PLEASE NOTE: Publication of your manuscript will not proceed until figures suitable for reproduction are received. Also, the author is responsible for obtaining permission to reproduce a graphic from copyright holders. Please see the 'Permission information' below.
