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
backgroundThe Columbia-Suicide Severity Rating Scale (C-SSRS) is the gold standard for assessing suicidal ideation, behavior, and risk. However, it is unclear whether the Patient Health Questionnaire-9 (PHQ-9) item 9 alone is sufficient for detecting suicidal ideation among patients with breast cancer. This study aimed to assess the validity of PHQ-9 item 9 compared to C-SSRS in female breast cancer patients undergoing psychiatric treatment.
methodsIn this study, we evaluated the validity of PHQ-9 item 9 compared to C-SSRS for identifying suicidal ideation among 176 female patients with breast cancer receiving psychiatric treatment, using self-reported questionnaires and leveraging demographic, clinical data, and statistical analyses to refine suicide risk assessment methods.
resultsAmong 176 patients, 35.2% showed a positive response to PHQ-9 item 9, 41.0% and 17.0% of them showed a response indicating
