1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

rationaleA dopamine receptor 4 variable number tandem repeat (DRD4 VNTR) polymorphism has been related to reactivity to smoking cues among smokers, but the effect of this genetic variation on brain responses to smoking cues has not been evaluated.

objectivesThe present study evaluated the relationship between carrying the DRD4 VNTR 7-repeat allele and transient functional magnetic resonance imaging (fMRI) blood-oxygen-level-dependent responses to smoking cues among adult dependent cigarette smokers. MATERIALS AND

methodsSmokers (n = 15) underwent fMRI scanning after 2-h abstinence. During scanning, they viewed visual smoking and control cues. A blood sample was assayed for the DRD4 VNTR polymorphism, and participants were categorized based on whether they carried one or two copies of the 7-repeat allele (DRD4 L, n = 7) or not (DRD4 S, n = 8).

resultsContrasts in brain cue-reactivity (smoking minus control cues) between DRD4 groups were conducted using SPM2. Smoking cues as compared to control cues elicited transient brain responses in right superior frontal gyrus (BA 8/9/10/32), left anterior cingulate gyrus (BA 32), and right cuneus (BA 19). Exposure to smoking cues resulted in greater activation of right superior frontal gyrus (BA 10) and right insula in DRD4 L compared to DRD4 S individuals. By contrast, exposure to smoking cues among DRD4 S individuals resulted in no significant increases in activation compared to DRD4 L individuals.

conclusionsThese brain imaging results suggest that DRD4 VNTR polymorphism is related to transient brain responses to smoking cues in regions subserving executive and somatosensory processes.
