CRP and deep vein thrombosis: The multivariate model, including mortality, length of stay, history of PE, peak ferritin, peak D-dimer, and peak CRP showed a history of PE (OR 6.80, 95%CI 1.18-39.34, p=0.032) and peak D dimer (OR 1.08, 95%CI 1.04-1.13, p<0.001) to be significant predictors of thrombosis in this population (Table 4).
