In comparison to WC, sIL-6R concentration was higher in BD- and BD+ (uncontrolled standardized β, respectively: β = 0.47, p < 0.001 and β = 0.42, p = 0.001; age and sex adjusted standardized β, respectively: β = 0.44, p = 0.001 and β = 0.37, p = 0.008). The gene discussed is IL6R; the disease is Behcet disease.
