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
Background: There is a lack of high-quality evidence to support the recommendation of an instrument to screen emergency department patients for their risk for violence. Objective: To demonstrate the content and predictive validity and reliability of the novel Risk for Violence Screening Tool to identify patients at risk for violence. Design and Setting: This retrospective risk screening study was conducted at a 100-bed emergency department in an urban, academic, safety net trauma center in Southern California. Participants: Nine subject matter expert employees and 22,583 non-critical adult emergency patients. Methods: Subject matter experts rated the relevance of 30 risk items and 10 domains comprising the Risk for Violence Screening Tool. Content Validity Index/Average Content Validity and Universal Agreement analyses determined the tool's content validity. Predictive validity, analyzed with logistic regression, used data from a patient incidence of violence registry (an incident occurred or did not occur), compared with the Risk for Violence Screening Tool screening result (positive or negative). Response agreement among three nurses who independently utilized the Risk for Violence Screening Tool to assess the same patients upon their arrival at the emergency department determined inter-rater reliability. Results: The overall Content Validity Index was 0.84, and the item-level Content Validity Index and the universal agreement scores were 1.00, indicating perfect agreement on item relevance and a unanimous consensus among experts. Patients who screened positive on the Risk of Violence Screening Tool, indicating a high probability of violence, were 27.55 times more likely to commit an act of violence compared to those who screened negative (95 % CI = 24.73 to 30.70). The logistic regression model was statistically significant, (χ Conclusions: The Risk for Violence Screening Tool is valid and reliable. This standardized tool can be used in emergency departments as part of a robust violence prevention program, creating a safer workplace for both staff and patients. Tweetable abstract: The Risk for Violence Screening Tool (RVST) is a valid and reliable brief screener to identify emergency department patients at risk for violence. @dhs.lacounty @ijn2024.
