Figure 4From: Influence of early antioxidant supplements on clinical evolution and organ function in critically ill cardiac surgery, major trauma, and subarachnoid hemorrhage patientsSelenium, glutathione peroxidase (GPX), and zinc plasma concentrations in trauma and cardiac surgery patients. The thick vertical bar next to the y-axis shows the reference ranges. By two-factor repeated measures analysis of variance, the changes over time and the treatment effect (interaction time*group) were strongest in the cardiac group, with P < 0.0001 for the three variables, while in the trauma group, treatment effect was selenium P < 0.0001, GPX P = 0.0013, and zinc P = 0.0005.
