| Variables | Measurement stage | Supplement group (n=45) |
Placebo group (n=45) |
p-value |
|---|---|---|---|---|
| MMP2 | At the beginning | 986.27±108 | 996.27±75 | 0.6 |
| (ng/mL) | At the end | 980.33±100 | 1005±77 | 0.19 |
| p-value | 0.11 | 0.16 | ||
| MMP9 | At the beginning | 827±113 | 849±149 | 0.4 |
| (ng/mL) | At the end | 735±104 | 875±135 | 0.00a |
| p-value | 0.001b | 0.001b |
Notes:
a
p<0.05 in independent samples t-test between two groups;
b
p<0.05 in paired sample t-test vs baseline. The data are presented as mean ± SD.
Abbreviation: MMP, matrix metalloproteinase.
