DELETION
To examine the potential effectiveness of Radio‐Taiso, between‐group differences in outcome changes were estimated at 95% confidence interval. In addition, effect sizes for between‐group differences in outcome changes were calculated. Change in value was calculated by subtracting the follow‐up value from the baseline value. Missing data were treated using the list‐wise deletion method. Based on the intention‐to‐treat principle, a full analysis set with complete baseline and follow‐up survey data was used in the main analysis.
