  1. Values are expressed as mean ± SD. Significant differences between t = 0 week and t = 16 week in control group as well as in TCC group are indicated as follows: *p < 0.05; ‡p < 0.001, using paired-samples t-test. Significant differences between TCC group and control group at t = 16 week are indicated as p < 0.05, using independent samples t-test.
