Systematic Literature Review and Meta Analysis

Systematic literature review with meta analysis is one of the most important methods used to review the scientific evidence on a topic. It starts with a literature search. If you're in the medical world, that might mean using PubMed (but there are other search engines). The selected studies need to be appraised. Appraisal of papers is important because different study types may provide different strengths of evidence. So Randomised Control Trials (RCTs) provide very strong evidence while case control studies weak evidence. Meta analysis is the most common method to synthesise quantitative data. The synthesis is usually presented as a forrest plot. So if you're doing a PhD or any other research, doing a lit review is an important first step.

This is the most concise and comprehensive explanation of systematic review and meta-analysis I've ever seen. Thank you!

[@gregmartin]

Thanks to Nested Knowledge for the support

[@RestonRichard]

Dr. Martin is the best teacher I have ever seen. He is gifted beyond measure, in my view, in simply and clearly presenting even the most complex topics. I can't recommend enough that all students of public and global health follow his videos. I do ... after spending 45 years working in global health and can't thank Dr. Martin enough for all I learn from him.

[@gregmartin]

Thanks for that very kind comment Richard. A comment like that, from the man who wrote Global Health 101 is humbling beyond words.

You earned a new subscriber. Thanks so much for this brief and clear explanation. I always wanted to understand the relationship between systematic literature review and Meta Analysis and this video did me a big favour.

[@gregmartin]

Thrilled to have you on board! So glad the explanation clarified things for you. Welcome to the community, and thanks for subscribing!

[@japhettetsofack1795]

Thanks a lot for this very clearly presented content. It has been quite helpful for me, since I am currently writing a literature review.

[@gregmartin]

Glad it was helpful! I appreciate the feedback, Japhette :)

I have a question regarding a systematic review I want to conduct. I want to analyse both qualitative and quantitative studies as there aren't many RCTs on the subject I am researching. Should I do a mixed-method, convergent style systematic review combining a qualitative approach and using the PICO format and possibly a meta-analysis, then using the qualitative research to do an etiology review section using PEO (Population, Exposure and Outcome). Is this normally done or am I making it up and would you recommend it?

Thanks Greg for explaining in detail how to do a systematic literature review and meta-analysis. The last chart you show - at the bottom of it says, Favours duel chamber \ Favours ventricular. Can you tell me what this is please?

[@gregmartin]

Thanks for the question Rod. Those are the two interventions being compared in that review.
