Figure 1.

The effect of thrombolytic therapy on factor VIII (FVIII) activity (A) and von Willebrand factor (VWF) antigen levels (B). Results are expressed as median values and interquartile ranges (whiskers) as measured from samples taken on admission, immediately after thrombolysis and 24 h after thrombolysis. Upper and lower limits of respective reference intervals are indicated with dashed lines (FVIII activity: 60–168%, VWF antigen levels: 50–160%). Statistical significance was assessed using Friedman’s two-way ANOVA with Dunn–Bonferroni post hoc test. *p < 0.05, **p < 0.01, ***p < 0.001 as compared to values on admission.
