Fig. 4: Results of meta-regression in brain reactivity to nonsmoking reward-related cues in smokers.
From: Neural substrates of smoking and reward cue reactivity in smokers: a meta-analysis of fMRI studies
a The cluster within the striatum that showed greater activation in response to nonsmoking reward-related cues in smokers compared with healthy controls and the cluster within the striatum that showed differences in the meta-regression analysis with FTND score as a factor. b Forest plot of the mean ± variance of effect sizes for group differences in the striatum, estimated from individual studies with nonsmoking reward-related cue exposure.
