Dynamics of FXIII activity levels in severe COVID-19 patients. A FXIII activity levels as a function of time of hospitalization (in days). Dashed line, the lower threshold of normal FXIII activity range. B Duration of hospitalization In relation to FXIII measurement in severe COVID-19 patients with normal or with low FXIII levels (p<0.02). Normal FXIII activity was defined as activity level >79 %. Low FXIII levels were levels were defined as activity level <79 %. C Consecutive measurements of FXIII activity in 14 severe COVID-19 patients. Individual patients dynamics are shown (left), average FXIII and FVIII levels and significance are presented (right). The average interval between the two measurements is 6.1±3.4 days
