  1. Univariate and multivariate regression analysis showing regression coefficients (β) with standard errors (SE) and p-values, with p-values in bold for variables with p < 0.05. The β corresponds to the predicted change in TEG MA (mm) associated with one unit increase in fibrinogen, platelet count, FXIII and/or sCD40L.
