Based on the present sample size and the observed plasma levels for patients with and without verified thrombosis, there is a 20% chance (statistical power 20%; 1-p = 0.8) of not detecting a true difference and a 5% chance of detecting a false difference (α = 0.05) if the observations (i.e. Δμ) differ with endocan 0.7 pg/ml, E-selectin 8400 pg/ml, D-dimer 3.7 μg/ml and CRP 21 μg/ml. This evidence concerns the gene SELE and deep vein thrombosis.
