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
backgroundWorkplace violence remains a persistent threat in emergency departments (EDs), yet violence risk is often assessed only at triage as a single-time-point activity. In practice, risk frequently evolves during care, shaped by situational stressors and interactional dynamics. How frontline situational awareness can be translated into structured, actionable risk management within ED workflows remains insufficiently explored.
aimTo develop and pilot a nurse-led, triage-embedded, trigger-based pathway for dynamic violence risk management in the ED.
methodsA mixed-methods study was conducted. Quantitative data (September-October 2025) captured trigger-initiated reassessments using the Dynamic Appraisal of Situational Aggression (DASA) during routine care. Qualitative focus groups explored trigger recognition, reassessment decision-making, and feasible responses. Findings were integrated to inform pathway development and refinement, followed by a one-month pilot.
resultsAmong 8443 adult ED encounters, 172 (2.0%) involved at least one trigger-initiated reassessment. Reassessments most commonly occurred during waiting and transitional phases of care and were frequently associated with increases in DASA scores. Nearly all aggressive incidents occurred in encounters that underwent trigger-initiated reassessment rather than baseline triage assessment alone. Qualitative findings indicated that reassessment was prompted by cumulative behavioural, interactional, and contextual changes, reflecting nurses' situational awareness. Reassessment was valued for formalizing intuitive concern, supporting communication, and legitimizing proportionate early action, while feasible responses were concentrated at lower to moderate perceived risk levels.
conclusionsViolence risk in the ED is dynamic and closely linked to workflow and situational context. A trigger-based pathway that operationalizes nurses' situational awareness into structured reassessment and proportionate response may support earlier, more feasible violence risk management within routine emergency care. REPORTING
methodThis study was reported in accordance with relevant reporting guidelines for mixed-methods research, including the STROBE checklist for the quantitative component and the COREQ checklist for the qualitative component.
