1. I want this to be addressed in the introduction:
• Defining the problem. Why is this important?
• Research question: We want to find out whether or not there is a relationship between depression and vitamin D and if there is, how much does vitamin D affects the level depression?

I want the introduction part to be written from these articles:

2. I want this in the search strategy:
o Which databases and why? which keywords?
o inclusion and exclusion criterias.

o flow-diagram (to show how the articles were selected)

Here are the inclusion/exclusion criteria which were used in step two in the flow diagram to exclude 5 studies:
• RCT
• The study population (both cases and control groups) has to be D vitamin deprived and has depression.
• D vitamin supplementation: how much, how often, for how long?
• Adult population (+18 years)

Here are what we used as a database: cochrane controlled trials register.
theses databses have to be mentioned (we thought of using them but did not decide to use them as we only wanted Randomised controlled trials to be included, and the cochrane controlled trials register do offer only RCT that exist in all the other databses) PUBMED, EMBASE, GOOGLE SCHOLAR, WEB OF SCIENCE, CLINICALTRIALSREGISTER.EU and clinicaltrials.gov.

Here are ours search keywords: Vitamin D, Depression, Randomized controlled trials.
