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.

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
Relapsing polychondritis (RP) is a rare, immune-mediated disorder characterized by recurrent inflammation of cartilaginous structures, often affecting the ears, nose, and respiratory tract. Vestibular dysfunction in RP is uncommon but clinically significant, resulting from inner ear involvement. We describe a case of an 81-year-old man with RP who presented with fever, bilateral hearing loss, vertigo, and ocular inflammation. Bilateral otitis media with effusion (OME) was identified on imaging and otoscopy, precluding the use of caloric testing. Video head impulse test (vHIT) revealed bilateral semicircular canal dysfunction, with decreased vestibulo-ocular reflex gains and catch-up saccades. The patient was treated with corticosteroid pulse therapy, oral prednisolone, azathioprine, and bilateral myringotomies. While hearing thresholds improved significantly following treatment, vestibular function remained impaired on serial vHIT assessments conducted before and after therapy. This case highlights the utility of vHIT in assessing vestibular dysfunction in RP, especially when middle ear pathology renders traditional caloric testing unreliable. Compared to caloric testing, vHIT offers a minimally invasive, repeatable, and well-tolerated method for evaluating high-frequency vestibular function. Incorporating vHIT into the diagnostic and follow-up process may facilitate earlier recognition of vestibular involvement in RP and provide a useful tool for monitoring treatment response. Given that vestibular dysfunction may not improve in parallel with hearing recovery, early detection and longitudinal evaluation are essential for comprehensive patient care.
