Kaplan–Meier Survival for ARDS Patients. Kaplan–Meier survival curves for patients with low (< 25.5 mg/dl) and high (≥ 25.5 mg/dl) daily glycaemic variability (DGV). Each cross on a curve represents a censored patient (survived to discharge), while each step in the curve represents a deceased patient. The x-axis represents the time in days to discharge. Survival curves were compared, and p-values calculated by log-rank test.
