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

rationaleResearch suggests that nicotine deprivation among smokers is associated with lesser resting cortical activity (i.e., greater power density in theta and alpha-1 EEG bands and lesser power in beta bands). These changes in cortical activity may be indicative of withdrawal-related cognitive deficits, yet the markers of differences in cortical activity are not well-established.

objectiveThe objective of the study was to clarify the EEG frequency bands affected by nicotine deprivation and assess prospective moderators.

methodOne hundred twenty-four heavy smokers visited the laboratory on two occasions following overnight smoking/nicotine deprivation. Prior to collecting 3 min of resting EEG data, participants smoked two very low nicotine cigarettes (<0.05 mg nicotine yield) at one session and two moderate nicotine cigarettes (0.60 mg nicotine yield) at the other.

resultsTheta and alpha-1 band (4-7 and 8-10 Hz) was greater in the very low nicotine (deprivation) relative to higher nicotine (satiation) condition. There were no condition differences in the beta-1 and beta-2 bands (14-20 and 21-30 Hz).

conclusionsGreater slow wave resting EEG may serve as a reliable marker of decreased cortical activity during smoking deprivation and, in turn, of withdrawal-related deficits in cognitive functioning. This research may inform the development of adjunct strategies for smoking cessation.
