Figure 1.

Univariate logistic regression analyses for the presence of active tissue factor (TF), activated factor XI (FXIa) or factor IX (FIXa). Detection of TF, FIXa or FXIa in anticoagulated patients with permanent atrial fibrillation is predicted by elevated vWF, IL-6, CAD, use of ACEI and/or aspirin, while current smoking and statin use are associated with the absence of any of these factors in circulating blood

The graph with logarithmic scale shows point estimates of odds ratios with 95% confidence intervals. vWF – von Willebrand factor, IL-6 – interleukin-6, CAD – coronary artery disease, ASA – aspirin, ACEI – angiotensin-converting enzyme inhibitor, F – factor. *p < 0.05.
