From: Changes in central venous saturation after major surgery, and association with outcome

Central venous saturation (ScvO2) in the 8 hours after major surgery. Results are means ± SD. *p < 0.0001 for low ScvO2 group; p = 0.02 for high ScvO2 group. The difference between the high and low groups is significant overall and for each individual time point (p < 0.0001).
