IL6 and deep vein thrombosis: In univariate logistic regression analysis, admission to ICU, anti-IL6 or anti-IL6R treatment and steroids use for COVID-19 were predictive of thrombosis occurrence, (p < 0.001, OR = 3.086, 95%CI 1.707‒5.578; p < 0.001, OR = 3.744, 95%CI 1.942–7.215 and p = 0.026, OR = 5.141, 95%CI 1.220–21.665, respectively).
