Umbrella reviews
Hi everyone,
I’m a medical student currently working on an umbrella review and I’ve reached the data extraction stage. I would really appreciate guidance from researchers who have experience with umbrella reviews or meta-research in medicine.
After my secondary screening I have around 20-25 articles (some only systematic reviews others have done meta analysis as well). Some of the metas have included the same 3-4 RCTS for the most part and there's quite a lot of overlap.
I am confused between running a qualitative synthesis (including all srs and srmas and just qualitatively reporting data) OR including only meta analysis and running a meta-meta analysis. What should help me decide the right approach for my data?
If I choose to go for meta - meta analysis ,which metas to choose when significant overlap.
Thankyou
