Crude: no adjustment. Model I: adjusted for history of smoking. Model II: adjusted for history of smoking, TXB₂, IL-10, and WBC. *: Females group is the reference group. CI: confidence interval; TFPI: tissue factor pathway inhibitor; FDP: fibrinogen degradation product; TXB₂: thromboxane B₂; IL: interleukin; WBC: white blood cells
