Treatment outcome measures
REGRESSION

Hierarchical linear modeling with random intercepts and slopes for pre- to posttreatment and pre-1MFU time-points, group, and their interaction predicting primary treatment outcomes.

Within-treatment group simple slope analysis of hierarchical linear modeling with random intercepts.
Abbreviations: β, beta regression weight; 
Time by treatment effect on FFMQ. 
Time by treatment effect on GAD dimensional severity. 
Time by treatment effect on PCQ-total. 
Time by treatment effect on inhibition. Table S2 of the Online Supplementary Material shows the maintenance of treatment gains on the above four measures.
