Supplemental Digital Content

Supplemental Digital Content

Authors may submit supplemental digital content (SDC) to enhance their article’s text and to be considered for online-only posting. SDC may include the following types of content: text documents, graphs, tables, figures, graphics, illustrations, audio and video. If an article with SDC is accepted, our production staff will create a URL with the SDC file. The URL will be placed in the call-out within the article. SDC files are not copy-edited by our staff; they will be presented digitally as submitted.

SDC Call-Outs

Supplemental digital content must be cited consecutively in the text of the submitted manuscript. Citations should include the type of material submitted (audio, figure, table, etc.), be clearly labeled as "supplemental digital content," and provide a description of the supplemental content. All descriptive text should be included in the call-out as it will not appear elsewhere in the article.

Electronic Figure Submission

  • Indicate what graphics program was used to create the artwork.
  • For vector graphics, the preferred format is EPS; for halftones, please use TIFF format. MS Office files are also acceptable.
  • Vector graphics containing fonts must have the fonts embedded in the files.
  • Name your figure files with "Fig" and the figure number, e.g., Fig1.eps.
  • Definition: Black and white graphic with no shading.
  • Do not use faint lines and/or lettering and check that all lines and lettering within the figures are legible at final size.

Line diagrams should be presented in a form suitable for immediate reproduction (i.e.not requiring redrawing), each on a separate A4 sheet. They should be reproducible to a final printed text area of 205 mm x 142 mm. Illustrations on disk should be supplied as TIF or EPS files at high resolution.
