Suicidal ideation and cognitive function: a comparative study in adolescents with unipolar versus bipolar depression.
Article in European archives of psychiatry and clinical neuroscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSuicidal ideation (SI) is highly prevalent in patients with depression and is closely associated with cognitive impairment. However, research focusing on this association within the adolescent population remains limited. Accordingly, this study aimed to investigate differences in SI levels and cognitive function between adolescents with unipolar depression (UD) and bipolar depression (BD), while further elucidating the associations between specific cognitive domains and SI.
methodsThis study recruited 326 adolescents with UD or BD. The Hamilton Depression Rating Scale (HAMD), Positive and Negative Suicidal Ideation Scale (PANSI), Insomnia Severity Index Scale (ISI), Internet Addiction Test (IAT), Positive and Negative Syndrome Scale Positive Subscale (PANSS-P), and Chinese Brief Cognitive Test (C-BCT) were used to assess depression, SI, insomnia, internet addiction (IA), psychotic symptoms, and cognitive function, respectively. Additionally, stepwise linear regression analysis was performed to identify independent factors associated with SI.
resultsCompared to the UD group, adolescents with BD demonstrated significantly higher scores on the HAMD, PANSI, IAT, and PANSS-P, alongside lower performance in attention, working memory, and executive function. Regression analysis identified HAMD score and working memory as independent correlates of SI in the UD group. In contrast, SI in the BD group was independently associated with females, HAMD score, IAT score, and working memory. LIMITATIONS: Given the cross-sectional design, determining causality from these findings is not feasible.
conclusionAdolescents with BD may exhibit more severe SI and greater cognitive impairment than those with UD. Across both groups, SI was strongly associated not only with clinical symptoms such as depression and IA but also with cognitive deficits, particularly in working memory. However, multicenter longitudinal studies are still needed to validate these findings.
