Statistical analysis All data will be analyzed statistically using Statistical Product and Service Solutions 10.0 software. Quantitative baseline data will be compared using two-sample t-tests and Mann-Whitney U tests, and qualitative data using χ2 or Fisher's exact probability tests. Differences in VAS and Harris scores between the iodophor-impregnated and iodophor-free adhesive drapes groups will be evaluated by two-sample t-tests. Non-normally distributed data will be converted or comparisons of primary and secondary outcomes prior to and after interventions will be compared between the groups using two-sample t-tests. Bacterial detection rates in peri-wound tissue and grade I wound-healing rates between the two groups will be compared by χ2 tests. A level of P < 0.05 will be considered statistically significant.
