How this list was built

We searched Europe PMC for English-language papers published since 2016 whose title contains “omega-3” or “fish oil” or “eicosapentaenoic” or “docosahexaenoic”, kept meta-analyses, systematic reviews and randomised trials, then ranked them by study design first, then recency and citations. Retracted papers are removed.
