The Discussion Section Tells Us Where We Are
In the Discussion section of a research report, the study's results are situated for the reader in the context of past and future research, clinical evidence, and theory. The author must look forward and backward to demonstrate to what degree, if any, the present work has moved the science forward, and where the field should go next. This section may require more thought and effort than any other part of a manuscript.
If science is a long and winding road, and research is how we move forward on that road, then the Discussion section should show the reader on a roadmap (or GPS system) how far we have moved after the present study, if we have moved at all. Keeping this principle in mind, writers can craft accurate and useful Discussions.
