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

Metabolic dysfunction-associated steatotic liver disease (MASLD) progression exhibits significant sex differences, with males generally developing more severe disease. This study used an endothelial nitric oxide synthase knockout (eNOS KO) murine model to investigate sex-specific MASLD progression under a Western diet intervention. Magnetic resonance imaging (MRI) assessed body composition and liver and skeletal muscle fat fraction, revealing greater visceral fat, liver volume, and liver-to-muscle fat ratios in males. Dimensionality reduction and clustering analyses identified distinct sex-specific MASLD phenotypes and progression patterns. Histological evaluations confirmed greater liver damage in males, evidenced by higher MAFLD Activity Scores. These findings highlight the critical role of sex as a biological variable in MASLD pathology and emphasize the influence of body composition and fat distribution on disease progression. The study underscores the utility of advanced imaging and analytical techniques for refining non-invasive diagnostics and guiding sex-specific interventions, paving the way for personalized MASLD management strategies.
