Hello, I need to change my research paper into PICO format. I need the following

2. Literature Review that answers & supports PICO question

The paper may need a lot of editing I am content with Chpt I and Chpt II (Introduction & Literature review). What needs work is Chpt III. I have attached a draft and a syllabus. The syllabus is a guideline to how the paper ought to be written.
