An Educational Video Game in Trauma Triage at Nontrauma Centers: A Secondary Analysis of a Randomized Clinical Trial.
Trial report in JAMA network open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06063434 (Testing the Effectiveness of a Theory-based, Customized Video Game at Increasing the Implementation of Clinical Practice Guidelines in Trauma Triage), which is not on this map. Not yet cited in PubMed.
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.

Abstract
Importance: Understanding how behavioral interventions work and whom they help can increase their effectiveness. Objective: To evaluate the mechanism of action and heterogeneity of the estimated treatment effect of a customized video game (Night Shift) designed to recalibrate physician heuristics (pattern recognition) in trauma triage. Design, Setting, and Participants: This process evaluation of a randomized clinical trial was performed with a national sample of 800 physicians responsible for the triage of patients with trauma at the emergency departments (EDs) of levels III, IV, and V trauma centers and nontrauma centers in the US. Data were collected online from November 27, 2023, to March 11, 2024. Data were analyzed based on intention to treat. Interventions: Usual education or customized video game played for 2 hours. All participants completed a virtual simulation, mimicking 3 ED shifts. Main Measures and Outcomes: The intervention's mechanism of action was analyzed using signal detection theory, which describes decision-making as the product of perceptual sensitivity (the ability to recognize signal [severe injuries] and noise [minor injuries]) and decisional threshold (tolerance for false-positive or false-negative decisions). The heterogeneity of the estimated treatment effect was evaluated using prespecified subgroup analyses to test moderation by participant characteristics (ie, sex, age, and clinical volume). Findings were validated using a data-driven approach with bayesian additive regression trees. Results: The 800 participants (566 [71%] male; mean [SD] age, 43.8 [9.4] years) had mean (SD) professional experience of 12.0 (8.4) years, worked at nontrauma centers (488 [61%]) or at level III, IV, or V trauma centers (312 [39%]), and were board-certified in emergency medicine (673 [84%]). Most intervention participants (339 [85%]) played the customized video game for at least 2 hours or until they completed the content, and most (345 of 398 [87%] for the intervention and 231 of 397 [58%] for the control) used the simulation. Assignment to the intervention arm was associated with a reduction in undertriage (22% vs 38%; percentage point difference, 16 [95% CI, 15-18]; P < .001). The intervention was associated with a moderate increase in tolerance for false-positive decisions (intervention 0.14 SD units [95% CI, 0.07-0.22]; control 0.53 SD units [95% CI, 0.43-0.63]; Cohen d = 0.6) and a small improvement in the ability to recognize severely injured patients (intervention 1.00 SD units [95% CI, 0.94-1.07]; control 0.87 SD units [95% CI, 0.79-0.94]; Cohen d = 0.2). Limited heterogeneity of the estimated treatment effect was observed, although participants' clinical volume was associated with moderation. Conclusions: In this process evaluation of a randomized clinical trial, exposure to a theory-based video game was associated with liberalized thresholds for transfer and limited heterogeneity of the estimated treatment effect.
