As a rule of thumb, it’s best to assume that all studies like this are in mice or rats unless the headline specifically says “in human trials”. Murine studies are a dime a dozen and therefore it’s the default assumption when reading research papers. When human trials commence the fact that it’s in humans is a big part of the research and therefore paper titles.
