Comparison of infarct volume among treatment groups.

<p>(A) Geometric mean infarct volumes are compared among groups after log transformation to achieve normal distribution. Only the IA MSC_24 h group shows significantly reduced infarct volume as compared to the IA PBS_24 h. B, Frequency infarct map statistically comparing the location of the mean infarct volume in the IA MSC_24 h and IA PBS_24 h groups using color- coded representation of the percent of rats showing infarction in each brain region using “Fisher's exact test” with a color-coded representation of the “p-value”, the color bar in “1-p” format. Displays are in “Coronal presentation”; middle sections are selected. The IA MSC_24 h group shows a much reduced infarction frequency, particularly surrounding the core as quantized by the Fisher test.
