Obesity drives the link between liver fat and depression: Cross-sectional and prospective investigations.
Article in Diabetes, obesity & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimsInconsistent associations have been reported between steatotic liver disease (SLD) and depression. We aimed to investigate the cross-sectional and prospective associations between MRI-derived liver fat, SLD and depression. MATERIALS AND
methodsWe used UK Biobank data. Liver fat was measured with liver MRI proton density fat fraction. SLD was defined as liver fat ≥5%. Depression was identified through self-reported diagnosis and hospital records. We examined cross-sectional associations using logistic regression and prospective associations using Cox proportional hazards models, adjusting for potential confounders, including socioeconomic status, lifestyle factors and body mass index (BMI).
resultsParticipants numbering 36 587 were included (age 64.5 years, 51.4% females, 28.2% SLD), and of these, 2849 participants had prevalent depression, higher in individuals with SLD (9.1%) than in those without (7.3%). SLD was associated with 40% higher odds of depression (OR: 1.40 (1.29, 1.52)) after adjusting for age, sex and socioeconomic status, but this was attenuated (OR: 1.12 (1.01, 1.23)) after adjusting for BMI. In the prospective analysis (n = 33 762), 414 people received a new diagnosis of depression over a median follow-up of 4.5 years. SLD was initially associated with a 27% higher depression risk (HR: 1.27 [1.03, 1.56]), but this was no longer significant after BMI adjustment (HR: 0.93 (0.73, 1.18)). Liver fat (per 5% increase) was not associated with depression risk (HR: 1.02 (0.92, 1.12)). No sex differences were identified.
conclusionsThe association between liver fat and depression is likely due to reverse causation and the confounding effect of BMI.
