1 · What the graph read from it

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.

2 · The registry

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

Patients with metabolic dysfunction-associated steatohepatitis (MASH) often suffer from a broad range of extrahepatic symptoms including fatigue and pruritus. However, evaluating behavioral abnormalities in preclinical mouse models remains challenging due to the limitations of conventional short-duration behavioral tests. This study aimed to comprehensively profile 24-hour behaviors of a MASH mouse model using a high-resolution, artificial intelligence (AI)-based approach. C57BL/6J mice were fed a choline-deficient, L-amino acid-defined high-fat diet from 6 weeks of age. We recorded videos across the dark/light phases at 8, 10, 12, and 14 weeks of age and analyzed behaviors using a novel AI-based behavioral analysis system. Twenty-four-hour behavioral analysis revealed that this model exhibited decreased locomotor activity alongside increased grooming and scratching behaviors as steatohepatitis progressed. These mice also exhibited altered eating-drinking rhythms and rearing patterns. Notably, these behavioral changes may reflect symptoms observed in patients with MASH; for instance, the reduction in locomotor activity is indicative of a fatigue-related phenotype. This comprehensive profiling highlights that AI-based behavioral analysis can identify novel behavioral phenotypes, effectively bridging the gap between mouse models and humans.
