I am looking for a very specific information, but I was unable to find it anywhere. Can you help me? Is there a review in the literature addressing how the proportion of metagenomics-based and 16S-based (gut) microbiome studies changed during the last decade? I am looking for something like this, but this is not ideal because there they focused on NIH-funded studies and they merged 16S+metagenomics when evaluating trends in types of methodology.
Thank you for the examples. Sounds great! If this info is not available yet, evaluating trends in methodology in public repos is definitely the way to go, which seems something really fun to do.
