^aP < 0.05 statistical significance vs intervention group.

^bP < 0.01 statistical significance vs intervention group. Results are expressed as means and standard deviation. The t-test was used for between-groups comparisons, resulting in P values and 95% confidence intervals (CIs, in brackets). MMP: Matrix metalloproteinase; TIMP: Tissue inhibitors of metalloproteinase; CI: Confidence interval.
