Size, pain and erythema in the initial period and after plasma application, one hour, one day and one week.

Mean and Standard Deviation of Ulcer Size
Initial	6.9 ± 4.51 A
One hour	3.96 ± 3.1 B
One day	2 ± 2 BC
One week	0.03 ± 0.18 C
p	<0.0001
Mean and Standard Deviation of Pain
Initial	7.1 ± 2.5 A
One hour	1.5 ± 2.3 B
One day	0.2 ± 0.7 C
One week	0.06 ± 0.3 C
p	<0.0001
Mean and Standard Deviation of Erythema Size
Initial	2.1 ± 1.1 A
One hour	1.4 ± 1 B
One day	0.5 ± 0.6 C
One week	0.03 ± 0.18 C
p	<0.0001

Different letters = statistically significant differences. It was verified that, after one hour of plasma application, there was a substantial reduction in size and pain (ANOVA one-way test followed by Tukey).
