Supplementary materials
Supplementary materials could refer to data or other resources that are published as part of an article (so would have the same authors, date, and underlying source, but would be designated as supplementary material) or could refer to accompanying or linked materials (with different authors, title, date, etc). Therefore, when citing supplementary materials consider whether the materials are presented as part of the main article or as work that has been published independently from the main article.
For supplementary materials that are part of an article, cite the article as usual, but add the section name/number and title of the supplementary materials to the end of the reference. For further guidance and examples, refer to Citing Medicine: examples of citations to parts of journal articles.
For supplementary materials that are independent of the article, locate the primary source for the supplementary material and cite according to the reference type.
