Scheffe’s test for time effect	a > b > c, d

Time 2 was in the end of 4 weeks, time 3 was in the end of 8 weeks, and time 4 was in the end of 12 weeks.
Data were presented as mean ± SD.
𝑃 values are calculated for the comparison between MHGWT and placebo groups by independent 𝑡-test.
^∗∗∗𝑃 < 0.001.
a: time 1; b: time 2; c: time 3; d: time 4.
