Comparison of correlations. With 95% confidence, the actual differences in correlations between methods 2 to 4 (M2–4) are within the height of the plotted boxes. The unit of the y-axes is the Pearson correlation and ranges between −0.1 and 0.1. Above each plot, the confidence intervals are also given in numbers rounded to the nearest thousandth. The titles of the columns tell which correlation was used as minuend and the titles of the rows which correlation was used as subtrahend when calculating the confidence intervals. The planes denote a correlation difference of zero and are red when the confidence intervals pass through zero, indicating that the actual difference between the two compared methods might be zero. C (coronal), S (sagittal) and T (transversal) denote the orientation of the intracranial areas used
