VAS (mm)	58.86 ± 12.43	65.20 ± 15.34	63.13 ± 19.78	63.64 ± 15.15	0.745
PPI (score)	2.00 (2.00–3.00)	3.00 (2.00–4.00)	2.00 (2.00–3.00)	3.00 (2.00–4.00)	0.099†

Data are reported as mean ± standard deviation or median (interquartile range)
Data are analyzed using one-way ANOVA unless otherwise indicated
^†Kruskal-Wallis rank sum test was applied because the data did not satisfy the normality condition
PPI = present pain intensity; SF-MPQ = Short Form of the McGill Pain Questionnaire; VAS = visual analogue scale
