The differences of D-dimer levels.

(A) Plasma levels of D-dimer in patients with gastric cancer (1.25±1.08 µg/mL) were significantly higher than the values determined for control subjects (0.37±0.20 µg/mL) (P<0.001). (B) The mean plasma D-dimer level of patients with peritoneal dissemination was 2.20±1.51 µg/mL, a value that was significantly higher than the measured amount for patients without peritoneal dissemination (1.01±0.79 µg/mL) (P<0.001). (C) The mean plasma D-dimer level in surviving patients was 0.79±0.720 µg/mL, a value that was significantly lower than the amount determined for the deceased patients (1.36±1.13 µg/mL) (P<0.001).
