A guide to using AMA citation style

In-Text Citations

References within the text of the manuscript should be cited with superscript numbers in the order in which they appear in the manuscript.

Formatting Tips:

  • Place superscript numbers outside periods and commas.
  • Place superscript numbers inside colons and semicolons.
