Filter OpenAlex for RCTs, meta-analyses and systematic reviews

You can now filter all of OpenAlex by study design: randomized controlled trials, systematic reviews, meta-analyses and more. 21 million works, in every field and language, carry one. Our randomized-trial tags are 99.7% precise, and on the same papers they're more precise than PubMed's, long the gold standard.
