Fig. 2From: Accelerated activation of the coagulation pathway during cardiopulmonary bypass in aortic replacement surgery: a prospective observational studyComparison of thrombin–antithrombin complex (TAT) between the groups. a: TAT at the start of cardiopulmonary bypass (CPB) (1), at 1 h from the start of CPB (2), and at the end of CPB (3). b: The increase in TAT during CPB. □ (open column): valve surgery; ■ (closed column): aortic replacement surgery; x: outlier; Data are showed as box and whisker plots (25 and 75 percentiles, outliers). Outliers are showed as cases with values more than 1.5 times of box lengths from either end of the box. #: p < 0.05Back to article page
