Prospective Validation of a Suicide Event Risk Model in Transgender Patients.

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
Suicide risk prediction models offer a promising avenue for early intervention, but their effectiveness in underrepresented populations remain uncertain. This study evaluated VSAIL's, a real-world, externally validated, and deployed suicide risk prediction model, performance in predicting suicide risk among transgender individuals. Transgender individuals were identified from electronic health record data and transgender status was verified via manual chart review. Results indicated modest discriminative ability (AUROC=0.777, AUPRC=0.115), however, a high rate of false negatives (77%), and significant miscalibration (Brier=0.023, Spiegelhalter's z-statistic p<0.001) reduced clinical utility. Findings underscore the importance of targeted subgroup validation and highlight limitations of general population-trained models in accurately identifying suicide risk among transgender patients. They also suggest the need for ongoing algorithm monitoring and subgroup-aware modeling strategies to improve predictive equity in marginalized populations.
