Values presented are least-square means with 95% confidence intervals in brackets. The p value is for the ANCOVA comparing groups at each time point controlling for the baseline value.
*n=32 PBTs and 31 controls for the ABC at 6-month follow-up.
†n=31 PBTs and 31 controls for the ABC at 12-month follow-up.
