*p < 0.05. For all variables, but CGI-I, the comparisons are performed between time 1 or time 2 vs time 0, within each treatment group.
aAsterisk refers to the significance value (with Bonferroni’s correction) of the one sample t-test performed within the particular treatment group and time point, assuming the value of 4 as hypothetical mean indicative of no change (see Section “Materials and Methods”). Values of CGI-I significantly lower (or higher) than 4 indicate an improvement (or worsening) of the clinical global index over time.
#Greenhouse-Geisser correction for the sphericity assumption.
