Serum albumin (p = 0.55), blood urea (p = 0.85), creatinine (p = 0.11), uric acid (p = 0.40), HDL cholesterol (p = 0.16), WBC (p = 0.52), Hb (p = 0.28), Htc (p = 0.56), Plt (p = 0.29), ESR (p = 0.97), CRP (p = 0.09), AST (p = 0.76), ALT (p = 0.85), ferritin (p = 0.08), triglyceride (p = 0.71), THR (p = 0.50), and SII (p = 0.22) values were not significantly different among sacroiliitis patients with active lesions and the subjects with chronic lesions. Here, GSTM1 is linked to Sacroiliac arthritis.
