Data are represented as means ± standard deviation and mean change. P values indicate the intervention effects of changes in the intervention and non-intervention periods (combining group A and B) analyzed using a linear mixed-effect model. Changes in the intervention period were based on the 4-week follow-up—baseline examinations of group A and the 8-week follow-up—4-week follow-up examinations of group B. Changes in the non-intervention period were based on the 8-week follow-up—4-week follow-up examinations of group A and the 4-week follow-up—baseline examinations of group B.
