A practical guide for writing a PhD thesis.

There is an increasing number of PhD students in health sciences, but no formal reporting guideline for writing a thesis exists. This review provides a practical guide with an overview of the article-based/synopsis PhD thesis that consists of eight parts: 1) initial formalities, 2) introduction, 3) methodological considerations, 4) study presentations, 5) discussion, 6) conclusion, 7) perspectives, and 8) concluding formalities. It is elaborated with detailed information, practical advice, and a template, so the thesis complies with the demands of the Danish Graduate Schools of Health Sciences.
