Table 2.

Scoring for skin appearance by the clinical scoring scale (CSS) and for pain using the numerical rating scale (NRS).

Variable	Alv (Mean ± SD)	Control (Mean ± SD)	Alv-Control (Mean ± SD)	p-value
CSS	0.18 ± 0.05	0.20 ± 0.07	−0.02 ± 0.07	<0.0001
Pain (NRS)	0.09 ± 0.09	0.09 ± 0.09	0.00 ± 0.04	<0.0001

The Wilcoxon signed rank test for non-inferiority of Alv compared to control was significant (p < 0.0001), indicating that mean CSS and NRS values in Alv treated arms were not worse by more than one score point compared to control treated arms. Mean ± SD, PP collective, n = 18.
