Skeletal muscle abnormalities negatively linked to sleep disturbances in patients with liver cirrhosis: a cross-sectional study.
Article in European journal of medical research, 2025. 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
backgroundLiver cirrhosis, particularly in its decompensated stage, is associated with significant complications, including sleep disturbances. The relationship between sleep quality and muscle abnormality in patients with cirrhosis remains elusive. This study aimed to investigate the association between the Pittsburgh Sleep Quality Index (PSQI)-defined sleep disturbances and skeletal muscle abnormalities, including sarcopenia and myosteatosis, in a cohort of patients with decompensated cirrhosis.
methodsWe conducted a cross-sectional analysis of 505 adult patients with decompensated cirrhosis, excluding those with malignancy, acute-on-chronic liver failure, severe hepatic encephalopathy, or incomplete data. Muscle status was determined by the skeletal muscle index (SMI) and intramuscular adipose tissue content (IMAC) on computed tomography (CT), respectively.
resultsThe median PSQI score was significantly higher in patients with coexistent sarcopenia and myosteatosis compared to those with no or isolated muscle abnormality (P < 0.001). Multivariate analysis revealed that concomitant muscle abnormalities (OR: 3.48, P = 0.029) and body mass index (BMI) (OR: 0.95, P = 0.040) as independent predictors of poor sleep quality. Additionally, in the subgroup with preserved liver function and younger age, the differences in PSQI score across various states of skeletal muscle are more pronounced.
conclusionSkeletal muscle abnormalities are an independent risk factor for sleep disturbances in cirrhotic patients, highlighting the need for targeted interventions to mitigate muscle abnormalities and potentially enhance sleep quality in this vulnerable population.
