Means for neuroimaging predictor variables by abstinent versus non-abstinent subgroups for the 30 days prior to week 12 (CO confirmed), and comparisons between abstinent and non-abstinent (independent samples t-tests), assuming all dropouts were non-abstinent

		S-F mean (SD)	S mean (SD)	F mean (SD)	n
30dayPP at 12 wks	Abstinent	0.373 (0.267)	0.045 (0.305)	−0.329 (0.309)	24
30dayPP at 12 wks	Non-Abstinent	0.213 (0.287)	−0.011 (0.276)	−0.224 (0.296)	119
	p value/ t statistic	0.013/ 2.53	0.38/ 0.88	0.117/ −1.58

PP = point prevalence, CO confirmed = anyone with a CO > 10ppm at the 12 week visit were deemed Non-Abstinent regardless of self-report, SD = standard deviation, S-F = beta for degree of association of DMN component with smoke cues minus for food cues, S = beta for degree of association of DMN component with smoke cues, F = beta for degree of association of DMN component with food cues
