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
Background: Although there is extensive evidence linking cyberbullying perpetration to adolescents' suicidal ideation, studies have not yet explored the longitudinal relationship between cyberbullying perpetration and adolescents' suicidal ideation, nor have they elucidated the mechanisms underlying this relationship. To address these gaps, this study employed a three-wave longitudinal design to examine the relationship between cyberbullying perpetration and suicidal ideation among Chinese vocational school adolescents, and the mediating effect of depression and the moderating effect of need to belong (NTB) in this relationship. Methods: Using a cluster sampling method, 802 adolescents (M Results: The results demonstrated that (1) T1 cyberbullying perpetration positively predicted T3 suicidal ideation; (2) T2 depression fully mediated the relationship between T1 cyberbullying perpetration and T3 suicidal ideation; (3) T2 NTB moderated the indirect relationship between T2 depression and T3 suicidal ideation. Specifically, the relationship between T2 depression and T3 suicidal ideation was stronger for vocational school adolescents with high NTB than for those with low NTB. Conclusion: These findings indicate that cyberbullying perpetration impacts adolescents' suicidal ideation via depression, and that adolescents with high NTB are more vulnerable to suicidal ideation when experiencing depression. This research highlights the importance of adopting a depression-focused intervention, thus preventing cyberbullying perpetration from escalating to suicidal ideation among vocational school adolescents, particularly those with high NTB.
