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

objectiveAn important antecedent of substance use among young adults is intentions for use (e.g., planned vs. unplanned use). In contrast to previous theories, emerging evidence suggests planned use, rather than unplanned use, is primarily related to consumption and sometimes consequences. As this has been most recently investigated with alcohol-only use, there remains a limited understanding of planned versus unplanned cannabis use, as well as how cannabis consumption influences planned versus unplanned alcohol events.

methodUsing data from a 28-day ecological momentary assessment study in young adults (

resultsAlcohol models revealed that planned alcohol use was linked to greater alcohol consumption at the day level and higher likelihood of experiencing positive alcohol consequences at the person level. The use of cannabis on a drinking day was also positively associated with experiencing a positive alcohol consequence. There were no day-level associations between planned alcohol use and negative alcohol consequences. Cannabis models revealed planned use was associated with higher likelihood of experiencing a negative cannabis consequence at the day level but was not associated with cannabis consumption or positive consequences.

conclusionsThis study highlighted differences in planned alcohol and cannabis use in predicting consumption and related consequences in young adults. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
