SD, standard deviation

F, F for one-way ANOVA test, pairwise comparison bet. each 2 groups was done using post hoc test (Tukey)

p, p value for comparing between the three studied groups

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

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