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

BACKGROUND AND

objectivesThe anterior cingulate cortex (ACC) is hypothesized to be involved in decision making and emotion regulation. Previous observations of drug dependent individuals indicate that substance dependence may be associated with cingulum white matter abnormalities. The present study evaluated cingulum white matter in cigarette smokers.

methodsDiffusion tensor imaging (DTI) in adult tobacco smokers and healthy non-smoker controls (total N = 70) was performed in a 3T Siemens Trio MRI scanner.

resultsAnalyses of DTI tractography of the cingulum in tobacco-smoking individuals and controls indicated that tobacco abusers have significantly reduced fractional anisotropy (FA) in the right cingulum. In addition, FA in the left cingulum white matter was negatively associated with the number of cigarettes smoked per day and the Fagerstrom test for nicotine dependence, a self-report measure of tobacco dependence severity.

conclusionsThe white matter of the cingulum is altered in a non-symmetrical way in tobacco smokers. An inverse relationship between FA and reported number of cigarettes per day was observed. Previous studies have also noted altered neural connectivity in cigarette smokers using similar methods. Similar white matter differences in the cingulum have been observed in methamphetamine dependent individuals and patients with dementia, which suggests that the cingulum may be altered by mechanisms not specific to tobacco exposure. SCIENTIFIC SIGNIFICANCE: By better understanding the effects of tobacco abuse on the brain, we hope to gain insight into how drug dependence influences the neurological foundations of behavior.
