TABLE 9.

Comparison of orcein stain grading score and the mean area % of elastic fibers (orcein stain) before and after treatment.

STAIN	RANGE	MEAN ± SD
Orcein stain grading score
Before treatment	2–5	3.71±1.26
After treatment	1–5	2.88±1.31
p value*	0.001
Mean area % of elastic fibres (orcein stain)
Before treatment	0.17–3.65	1.41±0.97
After treatment	2.46–13.75	7.06±3.30
p value*	<0.001

SD: standard deviation

^*p value significant if <0.05.
