Figure 4. Relationship between mean prehospital SBP and ischemic stroke etiology.

Figure 4

Box-and-whisker plots of mean prehospital SBP by stroke etiology, defined according to TOAST classification. The p values were obtained by analysis of variance followed by Tukey post hoc test for independent comparisons between categories. *p < 0.001 for small vessel disease compared to cardioembolic and other determined etiology groups. **p < 0.02 for other determined etiology against all other groups. SBP = systolic blood pressure; TOAST = Trial of Org 10172 in Acute Stroke Treatment.
