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
backgroundThis study evaluates changes in bullying before (2009-2019) and after the onset of the novel coronavirus (COVID-19) pandemic (2021-2023) in grades 9-12.
methodsA repeated cross-sectional study analyzed data (2009-2023) from the Youth Risk Behavior Surveillance System. An interrupted time series analysis was conducted to estimate changes in the level of and the trend of bullying.
resultsSchool bullying (n = 123,952) decreased by 5.14 percentage-points following the pandemic, most pronounced among females (-8.76 percentage-points) and non-Hispanic Whites (-6.82 percentage-points). However, school bullying resurged as the pandemic subsided. While online bullying (n = 107,853) had no notable change during the mid-pandemic period, a stratified analysis revealed a 4.55 percentage-point increase among males and a 3.72 percentage-point decrease among females. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Bullying prevention efforts should move beyond individual-level interventions to address the structural features of school environments. The variations in trends across student populations suggest that targeted strategies that account for subgroup-specific vulnerabilities may be beneficial.
conclusionsThe COVID-19 pandemic was associated with short-term reductions in the level of bullying on school property. Future studies are warranted to further our understanding of the specific reasons for these changes, particularly regarding attitudes and behaviors.
