Monitoring of HLA-DR expression on CD14^HIGH and CD14^LOW monocyte subsets during and after surgery. Mean ± SEM corresponding to the mean fluorescence intensity (MFI) for HLA-DR expression on CD14^HIGH (A) and CD14^LOW (B) monocytes from patients undergoing abdominal aortic surgery (AAS, close symbol) or carotid surgery (CAS, open symbol) at T₁ (before anesthesia), T₂ (before incision), T₃ (before clamping), T₄ (after reperfusion), and on post-operative Days 1, 2, 4 and 7 (POD1, 2, 4, 7). The two curves in both panel A and B are significantly different (P = 0.001). * P < 0.05, ** P < 0.001 compared with the initial value (T1) for each monocyte subset. # P < 0.05, ## P < 0.01 and ### P < 0.001 when comparing the two groups of patients at one given time point.
