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
aimsThe current study measured the extent to which different neurobehavioral indices of incentive-motivational salience attribution to alcohol cues predict alcohol craving and consumption in the natural environment. DESIGN, SETTING, AND
participantsLaboratory study at a university in Missouri, USA, followed by a smartphone-based 21-day ecological momentary assessment (EMA) protocol. Participants were emerging adults (N = 218-268 [52-56% female], age 18-20). MEASUREMENTS: Participants completed an alcohol cue approach-avoidance task while their electroencephalogram (EEG) was recorded. Behavioral measures (response time) indexed the strength of cue-activated approach vs. avoidance tendency. Cue-locked event-related potentials provided EEG-based neural measures of motivated attention (P3 amplitude) and approach-avoidance conflict (N450 amplitude). From EMA, measures of alcohol consumption dynamics (as indexed by estimated blood alcohol concentration [eBAC], g/dL) during real-world drinking episodes were obtained, as were measures of alcohol craving (7-point visual analogue scale) dynamics during and outside these episodes.
findingsDifferent approach-avoidance task-derived behavioral and neural measures rank-ordered participants differently. Participants who approached alcohol cues more rapidly in lab subsequently showed steeper increases in craving (∆B ± standard error [SE] = 1.042 ± 0.499 point/hr), and eBAC (∆B ± SE = 0.046 ± 0.017 g/dl/hr), during real-world drinking episodes. Participants who avoided alcohol cues more slowly in lab also showed steeper increases in eBAC (∆B ± SE = 0.056 ± 0.017 g/dl/hr). Participants with larger P3 during alcohol cue approach in lab subsequently showed steeper increases in eBAC (∆B ± SE = 0.048 ± 0.017 g/dl/hr), as did those with smaller P3 during alcohol cue avoidance (∆B ± SE = 0.025 ± 0.017 g/dl/hr). Participants with smaller N450 during alcohol cue approach in lab subsequently showed steeper increases in craving during drinking episodes (∆B ± SE = 1.465 ± 0.607 point/hr). Tests examining lab-based neurobehavioral measures as predictors of craving dynamics during nondrinking moments, such as following incidental cue exposure, generally were inconclusive.
conclusionsIncentive salience toward alcohol may influence alcohol seeking (including craving) and alcohol consumption through distinct behavioral risk pathways in different people.
