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
backgroundBenign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, yet it remains underdiagnosed and undertreated in emergency departments (EDs). Despite evidence-based guidelines recommending bedside diagnostic maneuvers (Dix-Hallpike and supine roll test) and canalith repositioning maneuvers (CRMs), these are infrequently utilized, leading to unnecessary imaging, prolonged symptoms, and increased healthcare utilization.
objectiveThis study aimed to implement an educational strategy to improve the diagnosis and treatment of BPPV in the ED by increasing adherence to guideline-based practices.
methodsWe conducted a multicenter interrupted time series study from August 2020 to September 2023. The intervention, developed using the CAN-Implement framework, included online training, quick-reference tools, and a mobile app. Due to the COVID-19 pandemic, in-person training was canceled. The primary clinical outcome was the proportion of patients receiving the appropriate CRM based on positional test results. Implementation outcomes included fidelity, appropriateness, adoption, penetration, and system impact, reported using the Standards for Reporting Implementation Studies (StaRI) guidelines.
resultsWe included 1682 patients (1252 pre-intervention, 430 post-intervention). There was no significant change in the primary outcome (appropriate CRM use, OR = 1.08, 95% CI: 0.76-1.40). However, selective CT use improved (OR = 1.29, 95% CI: 1.09-1.49), supine roll testing increased from 14.2% to 23.5%, and neurology consults decreased from 7.1% to 4.0%. Documentation of diagnostic test descriptors improved, while neurological exam documentation declined.
conclusionThe intervention did not significantly increase appropriate CRM use but led to improvements in selective imaging, neurology consultation, and horizontal canal testing. Provision of educational tools alone was insufficient to overcome identified environmental barriers. To effectively improve BPPV management in the ED, future efforts should combine hands-on training with system-level supports and workflow integration.
