Although time-dependent repeated-measure analyses and Dunnett’s test were attempted (vs. data in week 0), analyses resulted in an error. Instead, summary scores in weeks 4, 8 and 12 were separately compared with the data in week 0 with paired t test, and none of them resulted in a significant outcome. Then, the interaction between intervention and time was evaluated
