Prehospital patients with acute isolated vertigo and imbalance referred for cerebral thrombolysis.

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
Introduction: Patients with acute vertigo and gait imbalance who are suspected of having a stroke, are increasingly referred to the hospital for intravenous thrombolysis treatment (IVT) with an increasing impact on the healthcare consumption. This study seeks to examine the medical feasibility of considering patients suffering from acute vertigo with imbalance in a prehospital setting without other neurological symptoms as potential candidates for IVT regarding its efficacy and impact on clinical outcomes. Methods: Patients referred for IVT with isolated vertigo as determined by the ambulance paramedics, were retrospectively enrolled from a single center. Patients were categorized by discharge diagnosis. Baseline characteristics were recorded. The Modified Rankin Score (mRS) was used to assess clinical outcomes. Results: 163 consecutive patients were included. Within this cohort, 5.5% were diagnosed with stroke, and 7.9% with suspected stroke. Among patients with (suspected) stroke, 59.1% received IVT. Among patients with (suspected) vestibular vertigo, 5.1% received IVT. Patients with (suspected) stroke exhibited higher National Institutes of Health Stroke Scale [NIHSS; Mdn 0 (Q1 0; Q3 1) and Mdn 2 (Q1 0; Q3 2.5)]. Additionally, walking ability did not significantly vary between patients with vestibular disease and stroke. The mRS scores after a 3-month period did not show significant differences between the groups. Conclusion: Accurately differentiating between central and peripheral causes of vertigo in the hyperacute setting is challenging and carries the risk of overreferral and overtreatment. Combined with the lack of evidence that IVT improves clinical outcomes in patients with isolated vertigo and imbalance, and the increasing demand for healthcare, the authors suggest not referring these patients immediately for IVT but to consider adequate training of the paramedics in-field and other routes of medical assessment and treatment.
