AMA Manual of Style [Print] by AMA Manual of Style [Online] by 
As with any formatting style, the AMA Style creates a system for authors to:
In order to accomplish both of those goals, AMA has a standard way to express citations so that readers know when a source of information is being acknowledge and recognize the parts of the citation so that they may successfully find it for themselves (reference list).
In AMA Style, authors only include citations on their reference lists if they have cited that work in their papers. In effect there should be a one-to-one correspondence between in-text citations and reference list citations. Every item on the reference list should appear in-text and vice versa.
Both AMA and NLM use numerical citations, but AMA uses superscript numbers (e.g. 1,2) to identified cited information for in-text citations.
“In the reference list, use the author’s surname followed by initials without periods” (1 Fischer & Frank, 2020). The entire list is arranged in numerical order, based on the order of appearance in the manuscript. We’ll go into more detail about the Reference Lists later.
