The experimental design included two independent factors, treatment (control and allogeneic collagen) and observation time (days 7 and 14); data were analyzed using two-way analysis of variance (ANOVA) to determine the main effects of treatment and observation time and their interaction on HIF-1\u03b1 and MMP-13 expression. Post hoc multiple-comparison analysis was performed to compare differences among the four experimental groups.
