Figure 2

Figure 2. Kaplan-Meier cumulative curves for occurrence of ipsilateral ischemic stroke. From: Lower stroke risk with lower blood pressure in hemodynamic cerebral ischemia.

The number of participants who remained event-free and available for follow-up evaluation at each 90-day interval is shown for each group at the bottom of the graph. BP = blood pressure.

Figure 3. Rate of recurrent stroke within 2 years in the 5 blood pressure groups as defined in the PROFESS study. From: Lower stroke risk with lower blood pressure in hemodynamic cerebral ischemia.

Kaplan-Meier estimates with vertical bars denoting standard error of the estimates.

Figure 1

Figure 1. Individual mean systolic and diastolic blood pressures for the 91 participants in the 2 Carotid Occlusion Surgery Study groups. From: Lower stroke risk with lower blood pressure in hemodynamic cerebral ischemia.

Vertical bars depict the mean systolic (top of bar) and diastolic (bottom of bar) blood pressure of each participant in the study. Those who experienced an ipsilateral ischemic stroke within 2 years of randomization are shown in black. Three participants had mean systolic pressures below 130 mm Hg but diastolic pressures greater than 85 mm Hg. They are just to the right of the dotted vertical line.
