Fig. 1From: Impact of early postoperative blood glucose variability on serum endocan level in cardiac surgery patients: a sub study of the ENDOLUNG observational studyGlycemia and coefficient of variability of blood glucose within 48Â h after surgery. CV is the coefficient of variability of blood glucose, defined as the ratio of the standard deviation of blood glucose to the average of blood glucose expressed in percent. Each bar represents the minimum, maximum and mean blood glucose values measured within 48Â h after surgery in each patient included in the studyBack to article page
