Venous thromboembolism was seen in 5.94% of the severe hospitalized COVID-19 patients and in 2.79% of the non-severe ones. D-dimer had the highest association with DVT in COVID-19 patients.  However, DVT and COVID-19 patients also had higher levels of white blood cell count, neutrophils, and C-reactive protein and lower levels of fibrinogen. In 104 of their venous thromboembolism cases, 88 were of DVT. This evidence concerns the gene CRP and venous thromboembolism.
