Does making early evening social plans impact alcohol use outcomes over evening hours?
Article in Drug and alcohol dependence, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Puropse: This study examined associations of evening plans to engage in different social activities with drinking behaviors and negative consequences experienced over weekend evening hours among underage young adults.
methodsEcological Momentary Assessment (EMA) data were collected from underage youth (19-20 years) in California in 8 evenings over 4 successive weekends. At 6pm, participants reported their social (i.e., any social plans tonight) and contextual (i.e., planning to be outside own home tonight) evening plans and whether they planned to drink that evening. They subsequently reported alcohol use and negative consequences within the past two hours at 8pm, 10pm, midnight, and the next morning. We used mixed effects logistic and negative binomial models controlling for demographics, history of alcohol use, drinking motives, and weekend day. Analyses were based on data obtained from 230 participants who reported on 1469 evenings.
resultsIn about 37 % and 46 % of evenings in which participants reported having social plans or plans to be outside own home, they reported no plans to drink alcohol, respectively. Social evening plans were positively associated with subsequent alcohol use (OR=3.312, p < 0.001), the number of drinks consumed (IRR=2.009, p < 0.001), and the number of negative consequences experienced (IRR=1.526, p < 0.05), independent of plans to drink that evening. Having any social evening plans was positively associated with planned (vs. unplanned) drinking (OR=7.080, p < 0.001).
conclusionsSocial evening plans may be important determinants of drinking behaviors and negative consequences across evening hours among underage young adults. Results can guide future interventions to reduce heavier drinking and associated harms.
