ALB and susceptibility to pneumonia measurement: Patients with hypoalbuminemia were more likely to be intubated, and have pneumonia and cerebral vasospasm than patients with a normal albumin level on admission (43.6 vs. 8.9%, p < 0.001; 46.3 vs. 13.9%, p < 0.001; and 50.7 vs. 32.9%, p = 0.010, respectively; Table 2).
