Fig. 4From: Metabolomic profiling in patients undergoing Off-Pump or On-Pump coronary artery bypass surgery a Comparison of mean arterial arginine concentration measured at the beginning of the operation (1), after the first (2), second (3) and third (4) distal anastomosis in the On-Pump (white) and Off-Pump (black) group.* p < 0.001 and # p < 0.05. Data are presented as mean ± SEM. b Pearson correlation between postoperative noradrenaline doses and arterial arginine concentration measured at the time of the last distal anastomosis in the On-Pump (○) and Off-Pump (●) group including regression line and 95% confidence intervalBack to article page
