Post hoc analysis showed that adiponectin concentrations were more elevated in renal SLE patients than in HCs [19.0 (7.3–45.1) μg/mL vs 10.2 (1.6–23.4) μg/mL, p < 0.001] and non-renal SLE patients [19.0 (7.3–45.1) μg/mL vs 13.3 (0.6–37.0) μg/mL, p = 0.002]. This evidence concerns the gene ADIPOQ and systemic lupus erythematosus.
