Inter-group comparison of the clinical parameters readings, mean values ± standard deviation at 3 months after treatment.

Table 7: Inter-group comparison of the clinical parameters readings, mean values ± standard deviation at 3 months after treatment. Letters a, b, and c refer to the degree of significance at ^*P<0.05; significant difference was found among groups marked by different letters (a,b,c) and no significant difference was found among groups marked by similar letters.
