CRP and coronary artery disorder: Univariate analysis within the model group revealed the differences between the two subgroups of the DVT and non-DVT groups in terms of information (indexes) such as age, duration of surgery, time in bed, history of hypertension, history of coronary artery disease, history of perioperative blood transfusion, amount of postoperative drainage, whether or not hypothermia occurred intraoperatively, and the incidence of hypoproteinemia, D-dimer, and C-reactive protein levels on the first postoperative day was statistically significant (P < 0.05).
