Table 3 Statistical comparison of wound healing parameters from all valid check points – each checkpoint was treated as a distinct case, thus valid cases exceed number of patients and wounds. Due to the lack of a normal distribution in some parameters, the non-parametric Mann-Whitney U test was used. Statistically significant results are bolded
