A, In study 1 (cessation study), there was a significant indirect effect of IC task accuracy on smoking relapse outcomes via corticothalamic task-based functional connectivity (tbFC) such that increasing IC task accuracy and corticothalamic tbFC predicted maintaining abstinence (βi = −0.0078; bias-corrected and accelerated [BCa] 95%CI, −0.022 to −0.0002 [binary coding: abstinent, 0; relapsed,1]). B, In study 2 (laboratory study), the indirect effect of IC task accuracy via tbFC accounted for 51.7%of the total effect on time to smoke during the smoking relapse analog task (βi = 0.25; BCa 95%CI, 0.02 to 0.66). eTable 8 in the Supplement provides additional details.
