Treatment satisfaction

Groups	CON	SHAM	ESP	p-value
Assessed by patient	4 [4–5]*	5 [4–5]	5 [5–5]	0.001
Assessed by physician	4 [3–4]*	4 [3–5]	5 [5–5]	< 0.001

Data are shown as medians [interquartile ranges]. Probability was calculated with the Kruskal–Wallis test by ranks. If this test showed a significant result, a pairwise comparison was made with the Mann–Whitney U test. Significant calculated probability was set at 0.017 after the Bonferroni correction.
