Abstract

Summary Background The pathogenesis of non‐alcoholic fatty liver disease ( NAFLD ) is closely associated with the co‐occurrence of multiple pathological conditions characterising the metabolic syndrome (MetS), obesity in particular. However, NAFLD also develops in lean subjects, whose risk factors remain poorly defined. Methods We performed a meta‐analysis of 15 studies, along with the data pertaining to our own population (n = 336 patients). Data from lean (n=1966) and obese (n=5938) patients with NAFLD were analysed; lean (n=9946) and obese (n=6027) subjects without NAFLD served as controls. Results Relative to the lean non‐ NAFLD controls, lean patients with NAFLD were older (3.79±0.72 years, P =1.36×10 −6 ) and exhibited the entire spectrum of the MetS risk factors. Specifically, they had a significant ( P =10 −10 ) increase in plasma glucose levels (6.44±1.12 mg/dL) and HOMA ‐ IR (0.52±0.094‐unit increment), blood lipids (triglycerides: 48.37±3.6, P =10 −10 and total cholesterol: 7.04±3.8, mg/dL, P =4.2×10 −7 ), systolic (5.64±0.7) and diastolic (3.37±0.9) blood pressure (mm Hg), P =10 −10 , and waist circumference (5.88±0.4 cm, P =10 −10 ); values denote difference in means± SE . Nevertheless, the overall alterations in the obese group were much more severe when compared to lean subjects, regardless of the presence of NAFLD . Meta‐regression suggested that NAFLD is a modifier of the level of blood lipids. Conclusion Lean and obese patients with NAFLD share a common altered metabolic and cardiovascular profile. The former, while having normal body weight, showed excess of abdominal adipose tissue as well as other MetS features.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Normal-weight individuals with MASLD have a higher prevalence of metabolic alterations including insulin resistance, greater visceral obesity, and decreased muscle mass compared to normal-weight controls.

    “Normal-weight individuals with MASLD have a higher prevalence of metabolic alterations including insulin resistance, greater visceral obesity, and decreased muscle mass compared to normal-weight controls. 331,332”

    From EASL-EASD-EASO Clinical Practice Guidelines on the management of metabolic dysfunction-associated steatotic liver disease (MASLD). (2024) · cites this paper as [332]

    The Results (section 3.4) report greater insulin resistance and waist circumference in lean patients with NAFLD than in lean controls; section 4.3 interprets the waist difference as abdominal obesity. The paper does not establish greater visceral fat specifically or decreased muscle mass, so those parts of the claim are unsupported. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
