SD, standard deviation

H, H for Kruskal-Wallis test, pairwise comparison bet. each 2 groups was done using post hoc test (Dunn’s for multiple comparisons test)

p, p value for comparing between the three studied groups

p₁, p value for comparing between control and each other group

p₂, p value for comparing between cisplatin treated and PRP treated
