Fig. 3. The percentage of monocyte–platelet conjugates was measured before, during, and after cardiopulmonary bypass (CPB), shown relative to the percentage of monocyte–platelet conjugates at baseline. Measurements are presented as mean ± SEM. †P < 0.05 compared with baseline values. *P < 0.05 compared with the saline-only group. EACA =ε-aminocaproic acid.
