Are there any video Tutorials, Cochrane approved resource or any literature that can take step by step into doing systematic review and meta-analysis. I have found the right PICO details and have shortlisted my articles (which are RCTs). I have saved the full texts. Now how to formulate the right data gathering tool? And what are the statistical things I should be knowing in this process.
Considering its extensive nature, I am not planning to have a shortcut and will take months to revisit my extracted information, if I can be guided in the right direction.
Thank you.
