American Medical Association Style Example

The AMA style is radically different from APA. The in-text citations are superscript numbers and the References appear in order with the superscript numbers. Example paragraph with in-text citations. Note references don't have hanging indents and are in the order cited, not alphabetical order by authors last name.

Clinical trials are critical to advancing oncology care and their success is dependent on enrollment. In the United States, only 2–4% of newly diagnosed adult cancer patients participate in clinical trials.1 Manual screening for patient eligibility is expensive and inefficient.2 Automated systems to increase accrual to clinical trials are needed.

Clinical research informatics tools may improve the efficiency of identifying patients for clinical trials.3–5
