Regarding the predictors of moderate-to-severe NAFLD in RA patients, univariate regression analysis identified Gal-9, sTIM-3, and FABP1 as the potential predictors (OR: 4.87, p < 0.05, OR: 4.30, p < 0.05 and OR: 6.23, p < 0.05, respectively). The gene discussed is LGALS9; the disease is metabolic dysfunction-associated steatotic liver disease.
