As alcohol history contributed very little to the model, the remaining nine variables were selected for constructing the nomogram, including age, postoperative CRP, preoperative D-dimer, hemoglobin, and D-dimer postoperative Day-1, −3, −5, and −7 (Figure 3A), in which a higher score indicates an increased likelihood of DVT. The gene discussed is CRP; the disease is deep vein thrombosis.
