Beta 2 adrenergic receptor agonists as a treatment for metabolic dysfunction-associated steatohepatitis (MASH).
Article in npj metabolic health and disease, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
MASH is a leading cause of liver transplantation. Here, we investigated formoterol, a long-acting β2 adrenergic receptor agonist (LABA), in MASH. Mice treated with a high-fat diet (HFD) for sixteen weeks developed liver steatosis and were treated with formoterol or vehicle for four weeks. Steatosis largely resolved following formoterol treatment. To investigate mechanism, we evaluated mitochondrial biogenesis and found in HFD mice treated with formoterol versus vehicle that: PGC1α levels and electron transport chain components were significantly higher; mitochondrial number was increased; and lipids were decreased. Human HepaRG liver cells were then exposed to free fatty acids and/or formoterol. Formoterol attenuated lipid accumulation and increased ATP-linked basal and maximal respiration. Finally, a retrospective analysis of 59,644 patients with MASH showed that patients taking LABAs had fewer complications of advanced liver disease and lower mortality. Together, these data raise the possibility that LABAs, especially formoterol, could be a novel MASH treatment.
