LR identified the following four independent variables as predictive of SAP: albumin (OR 0.88, 95%CI 0.81-0.95, P=0.002), serum creatinine (OR 1.02, 95%CI 1.01-1.03, P=0.002), glucose (OR 1.15, 95%CI 1.07-1.24, P<0.001), and pleural effusion (OR 5.11, 95%CI 2.38-10.94, P<0.001). The gene discussed is ALB; the disease is Pleural effusion.
