Note. Only significant paths are shown to save space. Abbreviations: M3, M4, M5 = mediator measurements (taken at Weeks 4, 6, and 8, respectively); SE = standard error; T = Treatment allocation (treatment group = 1, control group = 0); Y2, Y3, Y4, Y5, Y6 = outcome measurements (taken at Weeks 2, 4, 6, 8, and 10, respectively).
