Rethinking Vertigo Evaluation in the Emergency Department: Why Diagnosing Benign Paroxysmal Positional Vertigo (BPPV), Not With Early CT or MRI, Most Effectively Reduces Diagnostic Error.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
In emergency departments, early CT or MRI is frequently used in the evaluation of vertigo, largely driven by concern for posterior circulation stroke. However, early CT is insensitive to posterior fossa ischemia, and early MRI may be falsely negative in the first 24-48 hours. In contrast, benign paroxysmal positional vertigo (BPPV), the most common cause of acute vertigo, remains underdiagnosed despite its characteristic clinical features and effective bedside treatment. This editorial argues that the dominant diagnostic error in vertigo care is not failure to detect rare central causes, but failure to actively identify BPPV. By re-centering vertigo evaluation on careful history-taking, positional testing, and recognition of canal-specific nystagmus patterns, before reflexive imaging, clinicians can reduce diagnostic error and unnecessary testing while maintaining patient safety.
