Table 4

Distribution of mean score (±st. dev.) for the items of PSAS, stratified for type of closure.

Type of closure		Pain score	Itching score	Color score	Stiffness score	Thickness score	Irregularity score	Total score	Overall opinion score
Octyl-cyanoacrylate	Mean	0.59	1.65	2.71	1.76	2.06	2.24	11.00	1.65
	St. dev.	1.1	2.5	2.7	2.4	2.6	2.4	9.8	1.6
Subcuticular suture	Mean	1.44	1.50	2.56	1.56	1.67	2.72	11.44	2.17
	St. dev.	2.3	2.2	2.2	2.5	2.2	2.6	11.5	2.0

Mann-Whitney 𝑈 test for independent samples: no significant differences in mean.
