A good way is to search for articles with "TOPIC" and "review" in the name on e.g. https://pubmed.ncbi.nlm.nih.gov/ or using a tool like https://inciteful.xyz/ (which was featured on HN some days ago). NCBI has an option for filtering by type of article, which includes reviews and systematic reviews.

These kinds of articles will then list relevant results, citing other relevant papers so you can continue going deeper from there.
