In terms of baseline characteristics, it was found that age, history of alcohol, FIB, hemoglobin, CRP, preoperative D-dimer, and D-dimer postoperative Day-1, −3, −5, and −7 were statistically different between the patients in the DVT and non-DVT groups (P < 0.05, Table 1). Here, CRP is linked to deep vein thrombosis.
