When data from only patients with the restrictive type were considered (Fig. 1B, sub-analysis 3), the model (p = 0.02, F = 2.7) showed that lower caloric intake (p = 0.04) predicted a lower nadir potassium level, with albumin having a tendency to affect nadir hypokalemia (p = 0.08). Here, ALB is linked to Hypokalemia.
