Scatterplots of the association between the observed CLT with the predicted CLT, using 2 different models, and with PAI-1. (A) Observed CLT plotted against the predicted CLT with the use of regression coefficients derived from a linear regression model, including levels of prothrombin, factor VII, factor IX, factor X, protein C, antithrombin, fibrinogen, plasminogen, α2-antiplasmin, TAFI, and PAI-1 (Table 2; model A). (B) Association between PAI-1 and CLT. (C) Observed CLT plotted against predicted CLT with the use of regression coefficients derived from a linear regression including levels of prothrombin, factor VII, factor X, factor XI, fibrinogen, plasminogen, α2-antiplasmin, TAFI, PAI-1, and a squared and cubic term for PAI-1 (Table 2; model B).
