Controls from the general population were age-, sex-, type 2 diabetes-, and BMI-matched at a 1:2 ratio. SLD was established using controlled attenuation parameter. Liver biopsies were obtained when significant liver fibrosis was suspected. Total RNA was extracted from freshly frozen cases and analyzed by RNA-seq.

Transcriptomic data was obtained in 109 patients and showed 87 significant genes differentially expressed between IMID-MASLD and control-MASLD.

Patients without cirrhosis showed better overall survival than those with cirrhosis (<em>p =</em> 0.043).

In this study, quantification of intracellular free FA and lipidomic analysis (triacylglycerol [TAG] composition, <em>de novo</em> synthesis products) was performed by Liquid chromatography–mass spectrometry (LC–MS); quadrupole time-of-flight liquid chromatography/mass spectrometry (Q-TOF LC/MS), respectively, in both SPH and MON cultures.</div></div><div><h3>Results</h3><div>Stem-like SPH showed a superior content of free FA (citric, palmitic, stearic, and oleic acids) and unsaturated TAG.

During a median 13.3-year follow-up, we observed 129 liver-related events. MetALD and ALD increased the age- and sex-adjusted liver-related outcome risk by fourfold (HR 3.83, 95% CI 2.51–5.84, &lt;em&gt;p&lt;/em&gt; &lt;0.001) and eightfold (HR 7.90, 95% CI 5.16–12.30, &lt;em&gt;p&lt;/em&gt; &lt;0.001), respectively, compared with patients with MASLD. ALD was also associated with the highest risk for non-liver mortality. Metabolic risk factors were present in 93% and 96% of individuals with ALT-defined SLD and ALD, respectively.
