The factors associated with mortality from the multivariate analysis were the presence of alteration of consciousness at first presentation (OR 11.24; 95% CI: 3.96–31.92, p < 0.001), having a malignancy as an underlying disease (OR 6.64; 95% CI: 1.83–24.00, p = 0.004), albumin ≤2.5 mg/dL at first presentation (OR 5.23; 95% CI: 1.71–16.02, p = 0.004), and having a respiratory tract infection (OR 5.07; 95% CI: 1.53–16.84, p = 0.008). The gene discussed is ALB; the disease is Respiratory tract infection.
