Data are presented as mean ± standard deviation, median with interquartile range between brackets, or frequency number with percentage between brackets. P values represent significance levels for comparisons between complete baseline and follow-up data using a paired t-test or Wilcoxon signed-rank test or for the fixed effect of time as derived from the linear mixed-model analyses with correction for baseline age, sex, and time-by-sex interaction. Values in bold indicate significance, P < 0.05
