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
backgroundThe increasing trend in suicides among young people emphasizes the urgent need for effective prevention strategies. Gatekeeper trainings (GKTs) equip individuals in a young person's network with skills to recognize signs of suicidal thoughts and behaviors, initiate supportive conversations, and facilitate referrals to appropriate care. This study examines the reach of a large-scale Dutch online-GKT in training both informal and formal gatekeepers.
methodsLongitudinal data were collected from Dutch adults who participated in the online-GKT between October 2022 and March 2023. Primary outcomes were self-reported knowledge and self-efficacy before and after the training. Secondary outcomes were training retention and behavior at 3-months follow-up. Repeated measures ANOVAs tested the effects of time, gatekeeper group, and interaction effects while logistic regression analyses explored predictors of gatekeeper behavior. Qualitative analysis examined emerging themes in narrative accounts of gatekeeper behavior.
resultsIn total, n = 8040 formal gatekeepers (e.g., healthcare workers, educational staff) and n = 1142 informal gatekeepers (e.g., family members, friends) participated. Gatekeepers showed significant improvements in self-reported knowledge (F(1,7555) = 8761.88, p < .001, η
conclusionsThese findings confirm the importance of online-GKTs in adolescent suicide prevention by reaching a large number of primarily formal gatekeepers and enhancing their self-reported knowledge and self-efficacy. Expanding online-GKTs reach to informal gatekeepers, particularly family members, is crucial given their pivotal role in youth suicide prevention. In addition, improving online-GKTs content to foster interpersonal bonds and promote accessible support resources (e.g., e-health, peer support) may further enhance gatekeeper responsiveness and intervention outcomes.
