Finally, in a stepwise manner, multiple logistic regression analysis was performed using DVT incidence as the dependent variable vs. the Khorana risk score, clinical profile (D-dimer, type of chemotherapy) and three possible biomarkers (sP-selectin, vWF:Ag, and ADAMTS) starting with a full model and then removing the nonsignificant variable one by one. Here, VWF is linked to deep vein thrombosis.
