FXII:Ag: Factor XII antigen; FXI:Ag: Factor XI antigen; DVT: Deep venous thrombosis; PE: Pulmonary embolism.

Table 3 Association between factor XII antigen and factor XI antigen and potential of deep venous thrombosis: Comparisons between deep venous thrombosis patients and controls

	Cut-off¹	Control	DVT	χ²	OR	95%CI	P value
FXII:Ag	≤ 63.331	42	35	0.942	1.453	0.683-3.092	0.332

FXI:Ag	> 100.905	15	20	1.401	1.614	0.729-3.576	0.236

¹Cut-off values for factor XII antigen (FXII:Ag) and factor XI antigen (FXI:Ag) were selected based on the 95^th percentiles of FXII:Ag and FXI:Ag in patients with deep venous thrombosis.

FXII:Ag: Factor XII antigen; FXI:Ag: Factor XI antigen; CI: Confidence interval; DVT: Deep venous thrombosis; OR: Odds ratio.
