Tobacco deprivation impairs metacognitive accuracy and cognitive flexibility.

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
rationaleTobacco dependence is characterized by a high relapse rate. It is thus important to obtain a better understanding of the cognitive precipitants of smoking relapses, and how these are changed under tobacco deprivation. Here, we provide evidence that tobacco deprivation impairs two cognitive processes important for successful smoking cessation: metacognition and cognitive flexibility.
methodsIn a pre-registered study following a within-subject design, persons who regularly smoke performed behavioral tasks measuring metacognition, motivation for mental effort, cognitive flexibility, and smoking lapses either in saturated or deprived states.
resultsWe found that tobacco deprivation not only increased the preference for immediate rewards but also impaired metacognitive knowledge about these preferences; strikingly, these metacognitive skills were moreover related to individual lapse behavior. While there was no evidence for deprivation effects on mental effort, tobacco deprivation also impaired the ability to overcome dysfunctional cue-reward associations, indicating deficits in cognitive flexibility.
conclusionsTaken together, the current findings deepen our understanding of how tobacco deprivation alters cognitive processes contributing to addictive behaviors in tobacco dependence, which may lead to improved interventions for smoking cessation.
