Post-treatment scores (mean ± standard deviation) and comparisons between groups (CS and PFS).

	Posttreatment values
	CS	PFS	Mean difference (CS–PFS)	p	95 % CI
					Inferior	Superior
VCSS	14.48 ± 2.66	18.50 ± 7,09	-4.02	<0.001	-6.35	-1.70
VEINES-QoL	80.09 ± 9.29	71.99 ± 11,28	8.01	<0.001	2.81	13.21
VEINES-Sym	82.11 ± 10.56	70.50 ± 14,80	11.66	<0.001	4.64	18.69

For the statistical analysis, a generalized estimating equation with a normal distribution and identity link function was used, assuming an AR(1) correlation matrix between the time points and Bonferroni multiple comparisons

CS, Conventional Surgery; PFS, Polidocanol Foam Sclerotherapy; 95 % CI, Confidence Interval.
