Figure 2. One-way sensitivity analyses of expected outcomes at hospital discharge after acute stroke of undetermined etiology with and without aspirin administration in the acute setting over the range of proportion of initial stroke due to intracerebral hemorrhage.

The x-axis indicates the proportion of initial strokes due to intracerebral hemorrhage (ICH). The y-axes represent (A) survival at hospital discharge (%); (B) risk of second in-hospital stroke (%); and (C) survival to hospital discharge without further stroke (%). The base case (34% of initial strokes due to ICH) is marked with an arrow. Treatment with aspirin is the preferred strategy for all outcome measures across the entire range of values for proportion of initial strokes due to ICH.
