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

While some types of rumination have been reported as exacerbating factors in depressive symptoms related to attention-deficit/hyperactivity disorder (ADHD) traits, the role of self-rumination remains underexplored. Additionally, self-reflection-a similar form of private self-consciousness which may have protective effects-has been even less examined. This study of 3,000 Japanese adults (aged 18-50 years) investigates self-rumination and self-reflection in depressive symptoms related to ADHD, using the Adult ADHD Self-Report Scale, Rumination-Reflection Questionnaire, and Beck Depression Inventory-II. Statistical analyses included Pearson's correlation and linear regression for mediation/moderation. ADHD traits were correlated with depressive symptoms (r = 0.413, p < 0.001), mediated by self-rumination (indirect effect = 0.21, 95% confidence interval [0.17, 0.26]). Self-reflection was positively correlated with depressive symptoms (r = 0.193, p < 0.001) but had a protective effect when controlling for self-rumination (β = -0.75, p < 0.001). Moderated mediation analysis showed self-reflection reduced depressive symptoms related to ADHD traits by moderating both the impact of ADHD traits on self-rumination and the influence of self-rumination on depressive symptoms. These effects were particularly significant for inattention traits. Our findings suggest that self-reflection, by mitigating self-rumination, may serve as a therapeutic target for depressive symptoms in adults with ADHD traits.
