  1. We select couple of sessions of the same patient with a delay of at least 16 days from the main dataset, Table 1. The last three columns report the Pearson coefficient correlation between the variable and the change in the clinical score between the two sessions. Correlations below the threshold \(r \sim 0.14\) are in parenthesis. Characteristics of second-order variables for this dataset are shown in Table 6 in Appendix
