Plasma sEPCR levels according to the genotype in 100 healthy male volunteers. The mean ± SD (n, range; median) was 79.4 ± 16.6 ng/mL (20, 56.4-108.2; 79.5), 84.6 ± 16.3 (48, 50.5-126; 82.9), 314 ± 218.7 (8, 211.3-854.4; 235.1), 85.5 ± 20.3 (18, 63.3-137.5; 77.8), and 196.7 ± 46.2 ng/mL (6, 138.4-266.5; 190.5) for A1 A1, A1 A2, A1 A3, A2 A2, and A2 A3 subjects, respectively. When excluding the subject with atypical high sEPCR levels (854 ng/mL), mean ± SD (n, range; median) of A1 A3 subjects was 237.9 ± 20.2 ng/mL (7, 211.3-274.9; 233.1).
