Visualization of the relationship between the tumor-tract-distance and the peritumoral FA-value. Correlation analysis confirms that there is a significant correlation between the distance and the peritumoral FA-value (Pearson's r = 0.594, p < 0.001) – even if the outlier is excluded when calculating Pearson's r (Pearson's r = 0.390, p = 0.036).
