Perilymphatic enhancement and endolymphatic hydrops: MRI findings and clinical associations.

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
Objective: In this study, we aimed to summarize magnetic resonance imaging (MRI) findings of perilymphatic enhancement (PE) and endolymphatic hydrops (EH) of the inner ear, which are associated with vestibular and cochlear symptoms. Methods: We analyzed data on ears with definite Meniere's disease (MD), sensorineural hearing loss (SNHL), vertigo, and listening difficulties (LiD) from 508 ears of 254 patients who underwent contrast-enhanced 3-Tesla MRI between April 2021 and March 2023. We evaluated the degree of endolymphatic hydrops (EH), signal intensity ratios (SIRs) between the basal turns of the cochlea and cerebellum, and hearing levels for all ears. Ears with definite MD were also assessed for changes in vestibular and cochlear symptoms within 6 months. Results: Ears with definite MD exhibited significantly higher percentages of EH in both the vestibule and cochlea compared with ears with other diseases. Furthermore, ears with MD or sensorineural hearing loss (SNHL) had significantly higher SIRs of PE compared with ears with other diseases or asymptomatic ears. Among patients with definite MD, those experiencing hearing fluctuations or vertigo attacks within the last 6 months had significantly higher SIRs of PE compared with those who did not experience any symptoms. Conclusion: Significant EH in the vestibule and cochlea was a major finding for the imaging diagnosis of definite MD. A high SIR of PE was a good indicator for assessing MD activity, reflecting vestibular and cochlear symptoms and fluctuations.Level of Evidence: 4.
