Plasma TAT complex following treadmill exercise. Healthy volunteers are represented by the grey boxes, and patients with intermittent claudication by the black boxes. A = baseline; B = immediately post-exercise; C = 1 hour post-exercise. Data presented as box-plots- line in centre of box represents the median value; the box represents the inter-quartile range and the whiskers represent the range. Markers out with the whiskers are outliers i.e. cases with values between 1.5 and 3 box lengths from the upper or lower edge of the box. P- values are Wilcoxon signed-rank test compared to baseline. Friedman test: P < 0.05
