M Mean, SD Standard deviation; Regression coefficient β0 is the baseline means for the control group; regression coefficients β1, β2 and β3 indicates the time effect observed for mid-intervention (β1), post-intervention (β2) and 4-week follow-up (β3); regression coefficients β4 is the mean differences in baseline scores between the experimental group and the control group; regression coefficients β5 indicates the mean differences between the experimental group and the control group between β0 and the value at mid-intervention (β5); regression coefficient β6, indicates the mean differences between β0 and the value at post-intervention (β6); last, regression coefficient β7, indicates the mean difference between β0 and the value at 4-week follow-up (β7)
