The Overlooked Diagnosis: A Case Report on Autonomic Dysfunction and Chronic Dizziness in an Elderly Patient With Neuroimaging Correlation.
Article in Cureus, 2025. 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
Dizziness is a common yet diagnostically challenging complaint in the elderly, often resulting from multifactorial causes such as vestibular dysfunction, autonomic impairment, and cerebrovascular disease. This case report describes a 74-year-old woman with persistent, non-vertiginous dizziness, exacerbated by postural changes, but without orthostatic hypotension or classic vestibular signs. Comprehensive evaluation, including autonomic function tests, tilt-table testing, and neuroimaging, revealed autonomic dysfunction and chronic small-vessel ischemic changes in the periventricular white matter, along with a small hypodense lesion in the pons. Specifically, the patient exhibited reduced heart rate variability, impaired parasympathetic reflexes, and cerebrovascular alterations suggestive of disrupted autonomic pathways. This case underscores the importance of integrating autonomic testing with neuroimaging to elucidate the underlying pathophysiology of chronic dizziness in elderly patients.
