Values are mean ± SD or median (interquartile range). Adjusted mean differences (90% CIs) were obtained from linear mixed-effect models with age, sex,baseline value of the outcome of interest, time, intervention, and the interaction time × intervention as fixed effects. * P < 0.05, ** P<0.01 (one-sided P values).
