The data correspond to a rating from 0 to 10 on a numerical rating scale, where 0 is the best and 10 the worst intensity, and are expressed in median [25th–75th percentiles]. The p value was calculated via Mann–Whitney-Wilcoxon test for nonparametric data and via Student’s t test for parametric data
The Italic, bold values are for significant p values
