Posting this because the summary going around does not say what the paper says, and the difference matters for how people here are using it.
The liver data is among the strongest non-weight findings in the class. The semaglutide MASH programme reported a large advantage over placebo on MASH resolution, with a substantial minority also achieving fibrosis improvement — and fibrosis is the endpoint that predicts outcomes. Mechanistically it is reduced hepatic lipogenesis, increased fatty-acid oxidation, less hepatic inflammation, and possibly a direct effect on stellate-cell activation.
Where I think it is weakest: the comparator does most of the work in how this gets reported, and it is not the comparator most people think they are citing.
What I am after is whether normalised enzymes tell you anything about fibrosis, and what the right follow-up measurement is. Happy to be told the question itself is wrong.
