Recurrence of benign paroxysmal positional vertigo: risk factors and outcomes.
Article in Revista da Associacao Medica Brasileira (1992), 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
objectiveBenign paroxysmal positional vertigo is the most common peripheral vestibular disorder. It can recur despite successful maneuvers. While various risk factors for recurrence have been investigated, these remain controversial. The aim of this study was to identify potential risk factors for benign paroxysmal positional vertigo recurrence and contribute to the development of preventive treatment strategies.
methodsThe study involved 301 patients who presented to our clinic with dizziness and were diagnosed with benign paroxysmal positional vertigo between December 2019 and May 2022. Two groups, with and without benign paroxysmal positional vertigo recurrence, were compared in terms of age, gender, hypertension, diabetes mellitus, hyperlipidemia, cardiovascular disease, asthma, hypothyroidism, magnesium deficiency, vitamin D deficiency, vitamin B12 deficiency, and iron deficiency to investigate the effects of these factors on recurrence.
resultsRecurrence was observed in 38 (12.6%) of the 301 patients. No age or gender difference was determined between the groups. Univariate analysis showed that hypertension (55.3 vs. 29.3%; p=0.003), vitamin B12 deficiency (21.1 vs. 6.5%; p=0.007), hyperlipidemia (26.3 vs. 5.7%; p<0.001), and asthma (15.8 vs. 5.7%; p=0.035) were more common in patients with recurrence. Multivariate logistic regression analysis identified only hyperlipidemia as a risk factor, raising the risk of recurrence approximately 3.7-fold (OR 3.71; 95%CI 1.36-10.13; p=0.011).
conclusionConsideration of underlying comorbidities and systemic factors, effective management of existing comorbidities, and individualized treatment strategies are crucial in order to reduce benign paroxysmal positional vertigo recurrence rates and improve patients' quality of life.
