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
backgroundSeveral studies have suggested a positive association between generalized anxiety disorder (GAD) and suicidal symptoms, particularly suicidal thoughts. Nevertheless, whether GAD is an independent risk factor for subsequent suicide is poorly understood.
methodsAnalyzing data on the entire Taiwanese population (N = 29,077,426), we followed 322,855 patients with GAD and 1,291,420 individuals without GAD matched for birth date and sex over the period from 2003 to 2017. Deaths by suicide were confirmed using Taiwan’s Database of All-cause Mortality. Psychiatric disorders comorbid with GAD were also assessed, specifically schizophrenia, bipolar disorder, major depression, alcohol use disorder, substance use disorders, obsessive-compulsive disorder, and neurodevelopmental disorders.
resultsA total of 2,051 (0.64%) individuals died by suicide in the GAD group, and 1,378 (0.11%) died by suicide in the control group. Cox regression models with adjustments for demographic characteristics, psychiatric comorbidities, and Charlson Comorbidity Index scores demonstrated that both men (hazard ratio [HR]: 2.64, 95% confidence interval [CI]: [2.29, 3.05]) and women (HR: 2.70, 95% CI: [2.33, 3.13]) with GAD were more likely to die by suicide than individuals in the control group DISCUSSION: GAD was a risk factor for death by suicide when controlling for various sociodemographic and clinical factors,including comorbid schizophrenia, bipolar disorder, major depressive disorder, and alcohol and substance use disorders.Suicide prevention strategies must be developed for individuals with GAD and associated psychiatric comorbidities.
