Starting on the left with all RBD patients included, this figure shows the Spearman´s rank coefficients of the correlation between APF and DaT-SPECT right caudate, left caudate, in subgroups of RBD patients by excluding patients based on their APF with increments of 0.1 Hz. Gray bars show the number of RBD patients included in the correlation. *significant correlation (p < 0.05).
