The solid thick lines indicate median values and the dotted lines indicate the values for the 10th percentile of the controls. The p-values shown are for the difference of median values between VTE patients and controls which was analyzed by Mann-Whitney test using Prism™ 4.03 software (Graph Pad Software Inc., San Diego, CA).
