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
objectiveTo psychometrically validate the Spanish version of the Paykel Suicidal Behavior Scale in the Mexican adolescent population, and to establish an optimal cut-off point to identify risk of suicidal behavior in school contexts.
methodsA cross-sectional study was conducted in 2022 with a non-probabilistic sample of 1,407 students from eight public high schools in the state of Morelos, Mexico. The mean age was 17 years, 58.7% were female and 41.3% were male. The students completed an online questionnaire that included the Paykel Suicidal Behavior Scale, the Center for Epidemiological Studies Depression Scale, and the Depression Anxiety and Stress Scale. A confirmatory factor analysis, item response theory, factorial invariance analysis (by sex, gender identity, and school grade), divergent validity analysis, and ROC curves were applied in this study.
resultsThe confirmatory factor analysis was found to be acceptable. The factor loadings ranged from 0.799 to 0.938. Item discrimination parameters were elevated (2.33 to 6.63), with difficulties ranging from 0.17 to 1.11. Factor invariance was confirmed in all subgroups. The divergent validity of the Paykel Suicidal Behavior Scale was satisfactory, as evidenced by its moderate correlations with the Epidemiological Studies Depression Scale (r = 0.507), depression (r = 0.644), anxiety (r = 0.570), and stress (r = 0.541). ROC analysis identified an optimal cutoff point of ≥ 1.0, with sensitivity of 75.93% and specificity of 76.54%.
conclusionThe Mexican version of the Paykel Suicidal Behavior Scale demonstrates robust psychometric properties, including validity, reliability, and factorial invariance in the adolescent school population. The scale's brevity, clarity, and ease of application make it an effective tool for school screening, allowing for timely detection and referral to mental health services. Its use is recommended in adolescent suicide prevention programs in educational contexts in Mexico.
