Moreover, low serum albumin level was associated with pneumonia, dyspnea, over 13-night long stay at ward, death at ward and serum CRP value over 100 mg/L in multivariable logistic regression analysis (P = 0.01, P = 0.02, P = 0.006, P < 0.0001 and P < 0.0001, respectively, Table 3). This evidence concerns the gene ALB and pneumonia.
