I have to add one page or even less but i need for you to review my paper and do the changes.
I would prefer if you use another color so I can see the changes.. I need to to proof read and make this changes Also you need your PICOT question as the problem statement somewhere around this area
You are missing levels of evidence in your literature review and you also need to add an intro paragraph about what Melynks hierarchy is. A paragraph of the level of evidence using Melnyk, B. M. & Fineout-Overholt, E. (2019). Evidence-based practice in nursing and healthcare: A guide to best practice (4th ed.). Wolters Kluwer. I also noticed in your synthesis review it is kind of hard to see your 3-4 themes and I don’t see any of I will need add 3 unanswered questions and recommendations that you need to have before the conclusion.
