Comparison between the three studied groups according to the change in plasma creatinine level and change in urea level between the 14th day and 1st day of the experiment

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 groups

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