Of these predictors, namely, pre-hospitalization ibuprofen intake, infective focus elsewhere, hypoalbuminemia < 3.1 g/dL, serum CRP > 20 mg/dL, Hb < 10 g/dL and total leucocyte count > 10,000 cells/μL, at least three were in line with our univariate analysis. The gene discussed is GSTM1; the disease is Hypoalbuminemia.
