^‡Note that the odds ratio corresponds to a unit increase in the explanatory variable.

^†Adjusted for those significant risk factors which confirmed in the univariate analysis, including age, history of vein thrombosis, clinical complications, rehabilitation therapy, plasma levels of CRP, IL-6, D-dimer and MIF

OR, odds ratio; CI, confidence interval; CRP, C-reactive protein; DVT: Deep vein thrombosis; MIF, Macrophage migration inhibitory factor; IL-6, Interleukin 6.
