LITERATURE REVIEWS survey scholarly articles, books and other sources (e.g. dissertations, conference proceedings) relevant to a particular issue, area of research, or theory, providing a description, summary, and critical evaluation of each work.
SYSTEMATIC REVIEW reviews literature focused on a research question that identifies, appraises, selects and synthesizes all quality research evidence relevant to that question. Systematic reviews of high-quality randomized controlled trials are crucial to evidence-based medicine.

6. Be Critical and consistent:
A reader should have an idea of

7. Find a logical structure.
It can be helpful to use a mind-map to draw a conceptual scheme of the review.
8. Make use of feedback. Can be peer-reviewed or someone reading a draft.
9. Include your own relevant research but be objective.
10. Be Up-to-date, do not forget older studies.
