Effects of pregabalin on smoking behavior, withdrawal symptoms, and cognitive performance in smokers.
Trial report in Psychopharmacology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
rationaleIn preclinical and clinical studies, medications enhancing the GABA neurotransmission attenuate nicotine reward. Pregabalin, a GABA analogue, presumably interacts with brain glutamate and GABA neurotransmission. The goal of this study was to determine pregabalin's effects on smoking behavior, nicotine withdrawal, craving for cigarettes, and cognitive performance.
methodsTwenty-four smokers participated in an outpatient double-blind, placebo-controlled, crossover study. Subjects had a 4-day treatment period with either pregabalin (300 mg/day) or placebo and following a washout period were then crossed over for 4 days to the other treatment. In each treatment period, starting at midnight of day 1, participants were asked to stop smoking until the experimental session on day 4. During the experimental session measures of ad lib smoking behavior, tobacco withdrawal, craving for cigarettes, and cognitive performance were obtained.
resultsPregabalin treatment, compared to placebo, did not reduce the smoking behavior during the first 3 days of treatment or during ad lib smoking period. Pregabalin treatment attenuated some tobacco withdrawal symptoms including ratings of anxious, irritable, and frustrated in abstinent smokers. Pregabalin treatment also attenuated the subjective ratings of "liking" in response to smoking. Under pregabalin treatment, smokers made more errors in a sustained attention task.
conclusionsThese findings provide limited support for pregabalin as a treatment for nicotine addiction.
