Q: Can you do a literature review for a systematic review study?
I am not entirely clear about your question. I am not sure if you mean ‘whether you should do a literature review for a systematic review study’ or ‘how can (should) you do a literature review for a systematic review study’.
A systematic review is a thorough and detailed review of existing literature on a particular topic, designed to address a specific question. This means that a systematic review will definitely involve doing a thorough literature review. However, for a systematic review, you start off with a clearly formulated question and your review of existing literature is directed at answering this question. This would mean that you use certain criteria to determine which studies to include in your systematic review and which to exclude. These are referred to as inclusion and exclusion criteria. Thus, a systematic review involves conducting a literature review, but with a specific study design in mind.
