Validity of the Tree Drawing Test Suicide Ideation Assessment Scale in adolescents.

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
Objective: To examine the validity of the Tree Drawing Test Suicide Ideation Assessment Scale (TDT-SIAS) for screening suicidal ideation in adolescents. Methods: A case-control design was employed, involving 36 adolescents with suicidal ideation and 58 adolescents without suicidal ideation. All participants completed the Tree Drawing Test, and their responses were analyzed using computer-based image recognition and data acquisition techniques with the TDT-SIAS. Statistical analyses were then conducted. Results: Significant differences were observed in total scores between the suicidal ideation group and the non-suicidal group (p < 0.001). Using a cutoff score of 9, the Youden Index was 0.901, with a sensitivity of 0.935, specificity of 0.966, positive predictive value of 0.956, and negative predictive value of 0.949. Inter-rater reliability (Cohen's kappa) ranged from 0.779 to 0.961. Conclusion: The TDT-SIAS demonstrated good screening performance and effectively distinguished adolescents with suicidal ideation from those without. It may serve as a preliminary screening tool for adolescent suicidal ideation. However, limitations of this study include the relatively small sample size and the lack of consideration for cultural differences, which may affect generalizability. Future studies should expand sample size and examine cross-cultural applicability.
