Note that the ATEC, SAS and PDD-BI are assessed at the beginning and end of the study, whereas the PGI-R is only assessed at the end, as it only evaluates the changes observed. Only the PGI-R found a significant difference between the supplement and placebo groups, so it is highlighted in a bolder font.
