ALB and Hypoalbuminemia: A study of patients aged 90 or more hospitalized with acute infection showed that 70 patients (43.2%) had hypoalbuminemia with a serum albumin level of less than 35 g/L and that the albumin level was independently associated with in-hospital mortality (OR: 0.86, 95% CI = 0.78–0.95, p = 0.004) [20].
