These results were derived through 2-way repeated-measures ANOVA.
Values are presented as mean±standard deviation.
PRP, platelet-rich plasma; SE, standard error; ANOVA, analysis of variance; HSD, honest significant differences.
At each time point, a post-hoc comparison was made using the Tukey HSD test.
a)Significant difference with the combined treatment; b)Significant difference with PRP-only; c)Significant difference with hydrogel-only.
