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: Suicidal ideation exhibits a strong correlation with mortality rates among individuals diagnosed with depression. Cognitive behavioral therapy (CBT) may exert an influence on suicide-related outcomes in patients with depression. We examined the impact of CBT on suicidal ideation and depressive symptoms in depression. Methods: By searching PubMed, Cochrane Library, EmBase, Web of Science, and PsycINFO databases (from inception to December 31, 2024), we identified randomized controlled trials (RCTs) of CBT for patients with depression. Suicidality was assessed explicitly as an endpoint utilizing clinically established psychometric scales with validated properties. The trials compared CBT for depression against control conditions in adults with depression, and reported findings pertaining to suicidal ideation. Independent pairs of reviewers were responsible for selecting studies and extracting relevant data. We evaluated the effects of CBT on suicide outcomes through random-effects model pairwise and network meta-analyses utilizing Stata 18.0. Risk of bias was assessed with the Cochrane risk-of-bias tool (version 2). Results: In this systematic review and network meta-analysis, 12 randomized clinical trials were selected from 14 articles (as 3 articles came from the same study and were therefore analyzed together), involving 1336 participants. In terms of suicidal ideation, after the intervention, CBT demonstrated comparable immediate efficacy in diminishing suicidal thoughts when compared to conventional treatment and the control condition. During follow-up, CBT was more effective than the control group (SMD=-6.98, 95%CI (5.71,8.24)). In terms of depressive symptoms, after the intervention, CBT had certain advantages compared with the control group (SMD = 3.11, P<0.05). During follow-up, CBT was more effective than the control group (SMD = 4.54, 95%CI (2.14, 6.95)). Conclusion: CBT may reduce suicidal ideation and depressive symptoms among patients with depression. However, more randomized controlled trials (RCTs) are needed to elucidate this effect. In psychological intervention trials for depression, monitoring and reporting of suicide-related adverse events should be enhanced.
