Discriminative Accuracy of Affective Temperaments in Assessing Suicide Risk.
Article in Psychiatry investigation, 2025. 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
objectiveThis study aimed to evaluate whether individual and composite scores of affective temperaments can differentiate high-risk suicide groups among patients with major depressive disorder (MDD) and to compare their discriminative accuracy.
methodsA retrospective review included 343 patients with MDD. Affective temperaments were assessed using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire, while the Depressive Symptom Inventory-Suicidality Subscale was used to classify the high-risk suicide group. Receiver operating characteristic (ROC) curve analysis assessed the discriminative performance of five individual and three composite scores of affective temperaments, with area under the curve (AUC). Logistic regression analysis was conducted to examine whether depressive temperament and composite scores independently predicted suicide risk.
resultsDepressive temperament demonstrated the highest discriminative accuracy among individual scores (AUC=0.754). All composite scores also showed good accuracy (AUC range=0.729-0.739). The results indicated that depressive temperament and three composite scores demonstrated good accuracy, with no significant differences between them. Additionally, irritable (AUC=0.660) and cyclothymic (AUC=0.650) temperaments exhibited sufficient accuracy. Logistic regression analysis indicated that only depressive temperament was a significant independent predictor of suicide risk.
conclusionDepressive temperament and composite scores demonstrated good discriminative accuracy for identifying high-risk suicide groups in MDD. These findings highlight the importance of assessing affective temperaments as stable traits for evaluating and predicting suicide risk. Future longitudinal, multi-center studies are needed to further explore the role of affective temperaments in predicting suicide risk among patients with MDD.
