Prefrontal Hemodynamic Changes Associated with Subjective Sense of Occlusal Discomfort

Figure 3

Results of channel-based correlation analysis between AUC and VAS scores. Upper panel: large, medium, and small circle diameters indicate values of less than 0.01, less than 0.05, and equal to or more than 0.05 at the corresponding channel, respectively. The color scale indicates the correlation coefficient. Lower panel: correlated relationship between individual tdVAS scores and AUCs in representative channels. indicates the correlation coefficient. Spearman’s rank correlation coefficient was calculated at channels 3, 8, 9, 10, 13, 14, 15, and 16 because data were not normally distributed. Pearson’s correlation test coefficient was calculated for the rest of the channels.
